Problems solved by technology

[0005] However, most of the existing cruise functions cannot judge the speed of obstacles in front and then take corresponding measures. When obstacles appear in front, the driver needs to continuously intervene in the operation, which is relatively cumbersome.
Moreover, the existing safety di

Embodiment Construction

[0050] The present invention will be further described below in conjunction with the accompanying drawings:

[0051] like figure 1 As shown, a vehicle adaptive cruise system includes an adaptive cruise mode selection unit 1, a data acquisition unit 2, an ECU central control unit 3, and an execution unit 4;

[0052] The adaptive cruise mode selection unit 1 is connected to the ECU central control unit 3, and the adaptive cruise mode selection unit 1 is used to select different adaptive cruise modes, and the adaptive cruise mode includes a constant speed cruise mode 101 and tracking mode 102, the ECU central control unit 3 controls the speed and distance of the vehicle in different adaptive cruise modes;

[0053] The data acquisition unit 2 includes the sensor 201 of the ESP, the vehicle radar 202 and the wiper sensor 303. The sensor 201 of the ESP includes a wheel rotation sensor, an acceleration sensor and a wheel speed sensor, and the wheel rotation sensor is used to collect...

Abstract

The invention belongs to the technical field of vehicle information, and particularly relates to a self-adaption cruise system and method. The system comprises a self-adaption cruise mode selection unit, a data acquisition unit, an ECU central control unit and an execution unit. A self-adaption cruise mode comprises a constant speed cruise mode and a tracking mode. Data of a front barrier are acquired through a vehicle-mounted millimeter wave radar and sent to the ECU central control unit, the front barrier can be automatically recognized, and the intervention operation of a driver is reduced through different measures; various information is acquired through an ESP sensor, addition of unnecessary hardware equipment is reduced, and the cost is saved; the influences, on a vehicle, of the outdoor sleety weather are considered for distance setting in the tracking mode, the tracking distance is automatically adjusted by an ECU, a one-time linear function is adopted for a time interval, a higher respond speed is achieved, and the riding comfort is considered as well. By means of the self-adaption cruise system and method, the driving fatigue of the driver can be effectively lowered, and meanwhile driving safety is improved.

Description

Technical field: [0001] The invention relates to the technical field of vehicle information, in particular to an adaptive cruise system and method. Background technique: [0002] Adaptive cruise control is a car feature that allows a vehicle's cruise control system to adapt to traffic conditions by adjusting speed. Different from the ordinary cruise control system, the adaptive cruise control system can automatically lock the speed of the vehicle in front and accelerate as the vehicle in front accelerates. Of course, the vehicle in front decelerates and decelerates accordingly. Drivers can take their feet off the pedals and just focus on the steering wheel, which can greatly reduce the fatigue caused by long-distance driving. [0003] To improve driver comfort, more and more cars are equipped with cruise control functions. The normal cruise function can effectively reduce the driver's operating burden to a certain extent through the control of the cruise speed, and at the ...
