Problems solved by technology

Driving for such a long time will cause driver fatigue and cause traffic accidents
[0003] The current form of automated driving is single, such as a single cruise control function, a single lane change function, a single auxiliary braking function, etc., and road driving is still controlled and driven by the driver
Especially for the situation of relatively simple highway road conditions, when the driver drives on the empty highway for a long time, due to the low degree of automatic driving, the driver needs to maintain a high degree of attention throughout the process and is prone to fatigue

Embodiment 1

[0028] figure 1 A schematic structural diagram of a vehicle control device provided in Embodiment 1 of the present invention. The device is located in a vehicle and includes: a gateway 101, a vehicle control unit (Vehicle Control Unit, VCU) 102, a full liquid crystal instrument IC 103, an electronically controlled brake System (Electric Braking System, EBS) 104, Electrohydraulic Steering System (Electric PowerSteering, EPS) 105, Hands Off Detection (HOD) 106, Smart Front View Camera CAMERA 107, Front View Millimeter Wave Radar RADAR 108, Fatigue Monitoring System (Driver Monitoring System, DMS) 109 and telematics processor (Telematics BOX, T-BOX) 110;

[0029] The vehicle controller VCU102 and the full LCD instrument IC103 are connected to the gateway 101 through the first bus 11;

[0030] Electronic brake system EBS104, electro-hydraulic steering system EPS105, steering wheel hand-off system HOD106, intelligent forward-looking camera CAMERA107, and forward-looking millimeter...

Embodiment approach 1

[0053] Embodiment 1: If an event affecting the vertical control is detected, exit the vertical control and horizontal control, and perform a three-level prompt.

[0054] Detect whether the data fed back by the vehicle controller VCU, the electronic brake system EBS, the intelligent front-view camera CAMERA, and the front-view millimeter-wave radar RADAR are abnormal. If an abnormality occurs, it is determined that an event affecting the longitudinal control is detected. The abnormality of the fed back data includes that the fed back data is not fed back according to the predetermined frequency, the fed back data exceeds the rated value range of the data, and so on.

[0055] Events that affect longitudinal control may cause the vehicle to fail to drive automatically, or fail to recognize the road conditions ahead. Therefore, the driver needs to take over the vehicle. At this time, exit the longitudinal control and lateral control, and perform a three-level prompt.

[0056] The...

Embodiment approach 2

[0057] Implementation Mode 2: When an event that affects lateral control is detected, exit lateral control and maintain longitudinal control; provide a second-level prompt; if the duration of the second-level prompt exceeds the second preset time, and the driver does not respond, then proceed to the third-level hint.

[0058] Detect whether the data fed back by the electro-hydraulic steering system EPS, fatigue monitoring system DMS, telematics processor T-BOX, etc. are abnormal. If an abnormality occurs, it is determined that an event affecting lateral control is detected. The abnormal data of the above modules will affect the lateral control. At this point, the horizontal control is exited, the vertical control is maintained, and the second prompt is output. If the duration of the second prompt exceeds the second preset time and the driver throws the vehicle and does not take over the vehicle, the prompt level is increased and a third prompt is output.

[0059] The above ...

Abstract

The invention discloses a vehicle control method, device and equipment. The method includes: after the vehicle enters the expressway, if the preset condition is met, enter the active cruise mode; in the active cruise mode, longitudinal control and lateral control are performed on the vehicle, Provide early warning prompts according to working conditions; determine whether to continue to implement the active cruise mode according to the driving conditions of the vehicle in front and the driver's control status; longitudinal control includes controlling the vehicle to perform constant speed cruise in the current lane or follow the vehicle in front; lateral control includes controlling when the vehicle is moving When turning, correct the direction of travel, and the current lane is the lane where the vehicle is currently located. It can reasonably enter and exit the active cruise mode, and realize automatic driving through longitudinal control and lateral control in the active cruise mode, realize reasonable use of automatic driving, improve the efficiency of automatic driving, reduce the workload of the driver, slow down the fatigue speed of the driver, and reduce the The incidence of traffic accidents.

Description

technical field [0001] Embodiments of the present invention relate to automatic driving technology, and in particular to a vehicle control method, device and equipment. Background technique [0002] As the main tool for road freight transport, trucks are an important link in the logistics supply chain. At present, almost all the vehicles on the roads in our country are traditional trucks, and the driver needs to continue to concentrate on driving the vehicle throughout the process. Driving for such a long time will cause driver fatigue and cause traffic accidents. [0003] The current form of automated driving is single, such as a single cruise control function, a single lane change function, a single auxiliary braking function, etc., and road driving is still controlled and driven by the driver. Especially for the situation where the road conditions of the highway are relatively simple, when the driver drives on the empty highway for a long time, due to the low degree of ...
