Embodiment 1
[0021] see figure 1 As shown, the present invention is a new energy passenger car steering wheel safety control system, which is composed of a steering wheel safety button, a vehicle controller, a relay, a servo motor, a steering wheel locking device, an instrument, double flashing lights, a motor controller, a drive Composed of motor and steering pump. Among them, the steering wheel safety button is an operation button set on the steering wheel, and the steering wheel safety button is used for the driver to press the safety protection button on the steering wheel for safety protection when the driver encounters unexpected passengers competing for the steering wheel;
[0022] The steering wheel safety button is communicated with the vehicle controller, and the steering wheel safety button is used to collect whether the driver presses the information. If pressed, it is transmitted to the vehicle controller through a high-level signal; the vehicle controller makes a decision on ...
Embodiment 2
[0033] A new energy passenger car steering wheel safety control system, the specific operation of the system includes the following steps:
[0034] S1. When the driver encounters others competing for the steering wheel, press the steering wheel safety button, the vehicle controller receives a high-level signal and enters the steering wheel safety control logic;
[0035] S2. The vehicle controller collects vehicle component information through the CAN line in real time, and at the same time turns on the relay to drive the servo motor to rotate forward. The servo motor is mechanically connected to the steering wheel locking device. Driven by the servo motor, the locking device locks the steering wheel , can not rotate, at the same time, the vehicle controller stops transmitting the speed command to the steering pump, so that the steering system loses power and quickly stabilizes the direction;
[0036] S3. At the same time, the vehicle controller transmits deceleration instructi...
