Problems solved by technology

[0005] At present, the automobile cruise control method for the automobile cruise control system includes: when the slope of the road on which the vehicle is driving changes, the cruise torque is adjusted, because the slope changes will cause the vehicle speed to change and deviate from the target speed range, in order to maintain the vehicle speed as soon as possible Target range, the cruise control system will adjust the cruise torque to make the acceleration and deceleration of the vehicle larger, which will cause the vehicle to run unsteadily and reduce the driving stability and comfort. Therefore, the current car cruise control system There is control hysteresis in the automobile cruise control mode

Embodiment Construction

[0031] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] figure 1 is a flowchart of a cruise control method for a vehicle according to an embodiment of the present invention.

[0034] Such as figure 1 As shown, the cruise control method of a vehicle according to an embodiment of the present invention includes the following steps:

[0035] Step S1: Obtain the current vehicle speed, the cruising target vehicle speed of the vehicle, and the slope information of the road ahead of the vehicle.

[0036] Specifically, the step of acquiring the gradient information of the road ahead of the vehicle includes: determining the position of the vehicle through a map; and obtaining the gradient information of the road ahead of the vehicle from the ...

Abstract

The invention provides a cruise control method and system for a vehicle and the vehicle. The method comprises the following steps that current vehicle speed, the cruise target vehicle speed of the vehicle and slope information of a road in front of the vehicle are obtained; the cruise torque of the vehicle is obtained according to the current vehicle speed and the cruise target vehicle speed of the vehicle; before the vehicle reaches the slope of a front road, the cruise torque is adjusted according to the slope information; and cruise control is conducted on the vehicle according to the adjusted torque, so that the cruise torque is adjusted in advance in combination with the current vehicle speed, the cruise target vehicle speed of the vehicle and the slope information of the road in front of the vehicle, it can be guaranteed that the cruise vehicle can stably adjust the vehicle speed when the road slope changes, and the driving stability and comfort of the vehicle are improved.

Description

technical field [0001] The invention relates to the field of vehicle technology, in particular to a vehicle cruise control method, system and vehicle. Background technique [0002] The car cruise control system is an automatic driving device that can make the car work in the favorable speed range of the engine, automatically maintain the speed according to the speed required by the driver, and make the car run at a fixed speed. [0003] In practical applications, when the car cruise control system is used on the vehicle, with the help of the feature of the car cruise control system, which can automatically control the vehicle to drive at a fixed speed, it is not necessary for drivers who need to drive for a long time. Requiring the driver to step on the accelerator pedal at all times, compared with the driver having to step on the accelerator pedal at all times, can effectively reduce the driver's driving and manipulation labor intensity. Unnecessary vehicle speed changes c...
