Why do I need an electronic gas pedal?

On the domestic auto electronic gas pedalbegan to establish relatively recently. For all this time, the smart pedal has managed to win not only fans of innovation, but also ardent opponents. Initially, Bosch in the development and implementation of the electronic gas pedal wanted to reduce harmful emissions into the atmosphere and reduce fuel consumption. Maseratty, Porsche and Mercedes have long ago picked up a new trend and began to produce already modernized cars, abandoning the pedal with a mechanical throttle.

What is the difference between electronic and mechanical pedals?

The mechanical pedal opens the throttlea damper per degree equal to the degree of depression of the accelerator pedal, thereby allowing the combustible mixture to enter the combustion cylinders. The electronic gas pedal does the same circuit, but in a slightly different way. The sensors, when the pedal is pressed, transmit a signal about the angle of pressing to the engine control unit. Based on these data, a smart car understands how fast the driver wants to start from the place, or how much he is going to accelerate, and decides independently whether it is worthwhile to cough up to her master. But that's bad luck! For a Russian man, accustomed to get off the ground with noise, screeching tires and a sharp push, such a sparing environment and fuel system turned out to be unusual. With the electronic gas pedal, car engines were also added the opportunity to make decisions independently without the driver's participation. So, if the machine understands that it is necessary to change the torque in order to save fuel or ensure safety, the control unit will simply change the position of the damper. Also, the electric winch will carefully turn the turns when there is an additional load on the engine. For example, if you turned on the air conditioner, opened the window or decided to use all the electronics installed in the car, at the same time, the revs on the tachometer will immediately let you know that the torque has been increased by the smart car. It can be safely stated that the electronic accelerator pedal has a place Only in the compartment with all the rest of the electronics: ABS, cruise control, air conditioning and so on. One electronics protects against drifts, the other - from heat, and the third - from quick starts and pollution of the environment, plus it allows the engine to work more economically, given how many different functions it supports and feeds in a modern car. Plus, the electronic pedal, in contrast to the mechanical, almost does not need to be repaired and replaced. Here the cable will not peretretsya, will not break and will not refuse on speed. Recently Russian craftsmen have started to invent all sorts of devices with the purpose to deceive electronics and to move from a place with a squeal and a roar. There are devices that force the electric motor to believe that the driver did not lightly press the gas pedal, but squeezed it out until it stops. Consequently, the fuel injection increases at times with the torque, and the auto tears and throws. But here there is a place to be another question - that the driver himself is prevented from pressing the accelerator pedal by pressing it into the mat?

Modern cruise control systems performseveral operations to establish the optimal speed of the car. For example, they accelerate or slow it down at 1 km / h by pressing a button. Thus, if you press the button five times in a row, the car will go 5 km / h faster. When the brake pedal is depressed, or when driving at 40 km / h, the cruise control system is automatically deactivated.

2

The cruise control system looks like a smallcomputer, which is usually located behind the dashboard or under the hood. It connects to several sensors on the main board computer and to throttle control. The throttle valve is controlled by means of a pneumatic actuator, and not by pressing the pedal. Also, the throttle valve regulates engine power by limiting the amount of air entering the engine. In good condition, cruise control can quickly accelerate the car to the desired speed, without exceeding and maintain with a slight deviation, regardless of the car's occupancy or the angle of the road.

3

Cruise control on most cars hascontrol consisting of the buttons On / Off, Set / Accel, Coast and Resume. If there is a manual gearbox, the system is connected to the brake pedal, the depressing of which leads to the deactivation of the cruise control. In vehicles with an automatic gearbox, cruise control is switched on and off by pressing the On / Off button. The Set / Accel car button allows you to maintain the current speed. Press again to accelerate by 1 km / h. The Resume function is used to automatically return to the speed at which the car moved to braking, and the Coast causes the vehicle to decelerate without the participation of the gas and brake pedals. Each press of this button causes a deceleration of 1 km / h.

You will need

• - cruise control (new or second-hand);
• - Torx bits with heads T15 and T30.

Instructions

1

Prepare everything you need to get startedinstruments. Check if the vehicle is de-energized. If there is any doubt, it is better to look at the battery and disconnect the negative terminal. It is necessary to do this in order to protect yourself from the operation of the emergency cushion in the Volga salon "Syber". Otherwise, the restoration of this security node will cost you a pretty penny.

2

Pay attention to numbers that you canto distinguish on each part used to install the cruise control. These numbers are extremely important, as, unfortunately, the device on this model can be assembled only from parts with specific numbers that are specified in the assembly instruction. Other, albeit similar, details will be useless. An attempt to adapt them in some way and still install a cruise-control will lead to the breakdown of the entire system.

3

Take the Torx with the heads of T15 and T30. Remove the cap from the emergency cushion. After that, remove the fasteners from the back of the steering wheel. In this place, the work can be stalled, since the screws are not visible, they are heavily recessed into the housing. We'll have to act almost blindly.

4

Carefully, trying not to act rudely, disconnect sufficiently loose connectors located on the airbag. Now you can pull it out and put it on the back seat of the car.

5

Connect the cruise control buttons to specialinternal connectors. Usually these connectors are marked in green, so it's almost impossible to miss them. After connecting, assemble the steering wheel in reverse order, without forgetting to reinstall the airbag.

6

Open the hood of the car. To operate the device you need to install a servo. Not far from the right glass of the shock absorber there are plugs that need to be removed and replaced with plastic inserts. If the inserts do not enter the holes, it is permissible to process them with light hammer blows.

7

Install a small plate for fixingServo and prevent its fall inside the engine compartment. Connect the drive to the original connector originally present in the machine wiring. Detect this connector can be on the main wires of the so-called "spit", where it is primed with an adhesive tape.

8

Route the servo to the gas pedal. Pay attention to the fact that to connect the drive to the throttle, you must first remove the regular cable.

9

To complete the installation procedurefor cruise control, connect the servo and vacuum brakes with a pipe using a special fitting. Then connect the battery negative terminal.

10

Start the car and turn on the cruise-control. A message appears on the dashboard indicating that the device is connected and operating normally.

Instructions

1

Stock up with all the necessary tools: jack, internal hexahedrons or mantles. Think about where it is best to make the removal of the gearbox - in a pit or on a lift. Plan your work so that you do it without haste.

2

Remove the hood and turn off the negativebattery terminal. Make sure that the pressure in the fuel system is minimized. Remove the battery and disconnect the wire from the cruise control unit, if any. Then remove the block.

3

Remove the starter, disconnect all hoses andwires that go from the gearbox, including fuel pipes that connect the engine to the body. Drain the coolant by turning off the radiator of the cooling system.

4

Carefully remove the shift lever cable. All mechanical control actuators must also be undocked. Secure the engine to the lift and remove the front wheels by loosening the bolts. Drain the transmission fluid, unscrew the bolts from the front engine mount. Remove the engine rear support.

5

Tie up to the body of the car steering gear, then unscrew the bolts. Under Automatic transmission put a jack, and unscrew all the necessary bolts,then lower the box. Take care of a careful descent, because rough handling can lead to breakage. For this operation, the transmission jack is the best.
