Autograde Safe Drive speed limiter
Safe Drive - a modern speed limiter, which is the only solution for cars with an electronic accelerator pedal. does not interfere with the operation of vehicle systems due to the lack of actuators with moving parts.
The device monitors and, if necessary, corrects the signal from the electronic accelerator by simulating the increase / decrease of the force of pressing the pedal by the driver and is protected from interference and burglary. Specially designed connectors prevent connection errors. Safe Drive is suitable for most modern vehicles.
The advantage of this limiter is the absence of interference in the fuel system of the car.
The use of limiters, where the actuator is a valve mounted on the fuel line, became impossible with the introduction of the Common-rail system on diesel engines due to the design features of the latter. Therefore, there is a need to find an alternative solution, which is currently Safe Drive.
The device receives a signal from the accelerator and duplicates it for consumers (ECU) until the speed programmed in the limiter is reached. Then, regardless of the input signal, the device begins to change the input signal so that the car's ECU begins to see the "release" of the accelerator pedal regardless of its actual position, and accordingly closes the throttle and reduces fuel supply, which reduces vehicle speed. After reducing the speed to a given value, the limiter again ceases to "control" the signal and duplicates it according to the actual value, allowing you to increase the speed to a given value.
