Embodiment Construction

[0022] The invention discloses an accelerator pedal 3 device for an unmanned racing car, including a control part and a drive part, wherein:

[0023] The control part includes an accelerator pedal angle sensor 8 installed at the rotating shaft of the accelerator pedal 3, which is used to acquire the position signal of the accelerator pedal 3 in real time and transmit it to the signal processor 9; the position signal refers to the accelerator pedal 3 The angular position of the rotation around its axis.

[0024] The signal processor 9 is connected with the CAN bus of the racing car, and is used to receive the desired acceleration signal from the CAN bus, convert the desired acceleration signal into the position signal of the accelerator pedal 3, and compare it with the acceleration obtained from the accelerator pedal angle sensor 8 The real-time position signal of the pedal 3 is compared, and the control signal is output according to the comparison result. The motor controller ...

Abstract

The invention discloses an unmanned racing car accelerator pedal device. The unmanned racing car accelerator pedal device comprises a control part and a driving part, wherein the control part comprises an accelerator pedal angle sensor and a signal processor; the accelerator pedal angle sensor is installed at a rotating shaft of the accelerator pedal and used for acquiring a position signal of theaccelerator pedal in real time and transmitting the signal to the signal processor; the signal processor is connected with a CAN bus of a racing car and used for receiving a desired acceleration signal from the CAN bus, converting the desired acceleration signal into a position signal of the accelerator pedal, and comparing the position signal of the accelerator pedal with a real-time position signal of the accelerator pedal obtained by the accelerator pedal angle sensor, a control signal is output according to the comparison result, a motor controller is used for controlling a servo motor torotate forward or reverse at the corresponding angle, and the servo motor drives the accelerator pedal to change angel positions through the driving part to control the movement of the accelerator pedal of a racing car. The acceleration mechanism is convenient to disassemble and assemble, is easy to control, is convenient to modify, and can realize acceleration and deceleration control over the racing car.

Description

technical field [0001] The invention relates to the technical field of bottom layer control of driverless formula racing cars, in particular to an accelerator pedal device for driverless racing cars. Background technique [0002] The University Formula Car Contest is hosted by the Society of Automotive Engineers of China. It encourages college students to build racing cars, cultivates students' innovative ability and teamwork ability, and promotes the spread of automobile culture in a novel way. The University City Formula Car Contest can be divided into three categories: gasoline vehicles, trams, and unmanned vehicles. At present, the acceleration function of the driverless mode of the formula car is mainly realized by using the original electric racing technology, that is, using the wire control technology to transfer the pedal position signal of the accelerator pedal sensor to the motor controller after A / D conversion. After continuous transmission, the ECU sends command...
