Vehicle driving intelligent assistance system

A vehicle driving intelligent assistance system, comprising:

• an electronic control unit and
• a Controller Area Network (CAN) module,
• wherein the CAN module is connected with a driving detection module (1), a vehicle body state detection module (2), an engine detection module (3) and an environment detection module (4);
• the driving detection module (1) is configured to acquire a driving speed and a wheel slip rate of a vehicle, and detect starting, driving and braking conditions of the vehicle, the vehicle body state detection module (2) is configured to acquire a steering angle of a steering wheel and suspension conditions, the engine detection module (3) is configured to acquire engine power data, and the environment detection module (4) is configured to acquire environmental information around the vehicle and road conditions;
• the electronic control unit is connected with a vehicle body stabilization system (6), a vehicle control system (5) and a lane departure early warning module;
• the vehicle body stabilization system (6) is configured to control braking of a driving wheel and an active wheel to improve anti-slip performance of the vehicle, and the vehicle control system (5) is configured to control acceleration, steering or braking of the vehicle to achieve assisted driving;
• wherein working steps of the assistance system comprise the following steps:
• when the vehicle is driving on a road, the environment detection module (4) detects a road environment and recommends different assistance modes according to driving road conditions, and the assistance modes comprise passive power-assisted driving, assistance power-assisted driving and active power-assisted driving;
• a driver selects a corresponding assistance mode as required, and when the vehicle runs normally, the driving detection module (1), the vehicle body state detection module (2) and the engine detection module (3) detect the driving state of the vehicle;
• according to different road conditions, the electronic control unit controls the vehicle body stabilization system (6) and the vehicle control system (5) to work, so as to ensure the stable driving of the vehicle;
• when the vehicle is driving at a high speed, the electronic control unit defines the steering wheel to prevent accidents due to the fact that the steering wheel is out of control and the vehicle deviates from the driving lane at the high speed;
• when the vehicle is driving on a rainy and snowy road, the electronic control unit controls the brake to prevent the vehicle from slipping due to brake locking;
• when the vehicle is driving on a dangerous road or a bumpy road, the electronic control unit assists in controlling and limiting the steering wheel and the engine, so as to prevent the vehicle from getting out of control due to the misoperation of the driver.
