ToF (Time of Flight) accelerator pedal. An accelerator pedal that works faster and more effectively using two ToF sensors
By employing ToF sensors with infrared technology in the accelerator pedal, communication errors and response time issues associated with conventional potentiometer-based systems are mitigated, resulting in improved reliability and reduced driver effort.

AI Technical Summary
Conventional accelerator pedals in vehicles rely on potentiometers, which can lead to communication errors and slower response times due to mechanical wear and pressure sensitivity issues.
The use of Time-of-Flight (ToF) sensors operating with infrared waves to measure the distance of the pedal's movement, providing faster and more reliable communication with the vehicle's control systems.
This solution significantly reduces the risk of communication errors and enhances response speed, allowing drivers to exert less pressure on the pedal while maintaining precise control.

Abstract
Description
[0001] The ToF accelerator pedal consists of several components: two ToF sensors, a control unit, a plastic accelerator pedal, and a spring. The pedal's use is similar to that of any other accelerator pedal in a car. After turning the ignition key, the control unit receives power and begins communicating with other control units in the vehicle.
[0002] The two sensors continuously transmit their measured values to the control unit, which processes them and forwards them accordingly. Two sensors are installed because a failure of the accelerator pedal must not occur under any circumstances. The sensors operate using infrared waves, which results in a very fast response. This also reduces the pressure the driver needs to exert on the pedal.
[0003] The pedal's design is identical to conventional accelerator pedals. The only difference is that the ToF accelerator pedal uses infrared sensors instead of a potentiometer. The two sensors are installed opposite each other and each measure the distance to the end of the pedal. Thanks to the infrared sensors, the risk of communication errors between the accelerator pedal control unit and other control units is significantly reduced.
