A vehicle speed and rotational speed signal transmitter and control method for eps debugging

Abstract

The invention discloses a vehicle speed and rotational speed signal transmitter for EPS (emergency power supply) debugging and a method for controlling the vehicle speed and rotational speed signal transmitter. The vehicle speed and rotational speed signal transmitter comprises a power management module, a microprocessor, a vehicle speed adjusting module, an engine rotational speed adjusting module, a CAN (controller area network) module and an output signal control module. The vehicle speed adjusting module, the engine rotational speed adjusting module, the CAN module and the output signal control module are respectively connected with the microprocessor; power can be provided for the microprocessor by the power management module, and adjustable vehicle speed value signals and adjustable engine rotational speed value signals can be respectively provided for the microprocessor by the vehicle speed adjusting module and the engine rotational speed adjusting module; vehicle speed CAN signals and rotational speed CAN signals can be outwardly transmitted by the microprocessor via the CAN module; control signals for determining whether vehicle speed and rotational speed signals are outputted or not and CAN signal protocol selection signals can be provided for the microprocessor by the output signal control module. The vehicle speed and rotational speed signal transmitter and the method have the advantages that the vehicle speed and rotational speed CAN signals and vehicle speed and rotational speed PWM (pulse width modulation) signals can be transmitted by the vehicle speed and rotational speed signal transmitter, computer resources can be saved, the vehicle speed and rotational speed signal transmitter is portable and is easy to operate, and visualization can be implemented.

Description

technical field [0001] The present invention relates to the technical field of debugging equipment, and more specifically, relates to a vehicle speed and rotational speed signal transmitter and a control method for EPS debugging. Background technique [0002] like figure 1 As shown, the normal operation of the EPS controller requires the torque angle signal of the torque sensor, the power supply of the vehicle, the ignition signal, the CAN speed signal and the motor signal. If the controller is installed on the whole vehicle, there is no problem in normal operation, because the whole vehicle can provide all the signals required for the controller to work. However, when debugging the EPS controller in the laboratory environment, since it is separated from the environment of the whole vehicle, although it can provide the torque sensor's torque angle signal, power supply, ignition signal and motor signal, but lacks the vehicle speed and rotation speed signal, the controller ca...
