Problems solved by technology

In recent years, in buses or buses, passengers and drivers have quarreled and robbed the steering wheel. The speed of the vehicle cannot reach a rapid decline, and under the action of inertia, the problem of collision will occur at a relatively fast speed, resulting in the loss of control of the vehicle and causing large or small traffic safety accidents

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...

Abstract

The invention discloses a new energy bus steering wheel safety control system. The system is composed of a steering wheel safety button, a whole bus controller, a relay, a servo motor, a steering wheel locking device, an instrument, a double-flashing light, a motor controller, a driving motor and a steering pump. The whole bus part information is in real-time communication with the whole bus controller; through components such as the steering wheel safety button, the whole bus controller and the steering wheel locking device, when a passenger fights for the steering wheel suddenly, a driver presses down a safety protection button on the steering wheel, the whole bus controller receives a signal, the current vehicle speed and direction condition are judged, then a servo motor is driven to work, and the steering wheel locking device is driven to lock the steering wheel. Meanwhile, the whole bus controller controls the double-flashing light and stabilizes the vehicle speed, and assists the driver in parking the vehicle stably. Traffic safety accidents caused by large-amplitude deflection of the steering wheel during fight are prevented.

Description

technical field [0001] The invention relates to the technical field of new energy passenger cars, in particular to a steering wheel safety control system for new energy passenger cars. Background technique [0002] Chinese patent CN105416232B discloses a monitoring system and method for preventing car steering wheel snatching. Through the snatching signal monitoring unit, it is monitored whether a car steering wheel snatching event occurs, and when a car steering wheel snatching event occurs, an effective snatching signal is generated; input to the controller , the controller generates a control signal according to the effective preemption signal; and inputs the control signal to the drive execution unit, and the drive execution unit generates an execution protection action according to the control signal. It can effectively monitor whether the steering wheel of the car is snatched in real time, and execute protection actions, which improves the driving safety of the car. ...
