Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] Embodiment of vehicle constant speed control method

[0034] The vehicle constant speed running control method provided by the present invention uses the throttle opening as the control amount to control, so as to realize the constant speed running of the vehicle. Aiming at the realization of constant-speed driving in the entire vehicle speed range, this method proposes different parameter settings in different speed ranges to achieve the purpose of fast response, stable and reliable, smooth and comfortable control of vehicle constant-speed driving.

[0035] It should be noted that the throttle opening referred to here is an electronic throttle opening, that is, a throttle opening expressed by an analog or digital electrical signal that can be received by the controller. This part belongs to the prior art and is no longer specific. illustrate.

Abstract

The invention relates to a vehicle constant-speed traveling control method and device. At least two speed intervals are divided between a speed lower threshold value and a set target speed, at least two speed intervals are divided between the set target speed and a speed upper threshold value, and the speed intervals are in one-to-one correspondence with accelerator open degree adjusting amounts;and when a vehicle speed is between the speed lower threshold value and the speed upper threshold value, as for each collecting period, the corresponding accelerator open degree adjusting amount is determined according to the speed interval where the actual speed of a vehicle is placed, and then the vehicle is controlled to travel according to the superposition value of the actual accelerator opendegree and the corresponding accelerator open degree adjusting amount. The effect achieved in the process is that the more the speed gets close to the target speed, the slower the speed change is; and the vehicle can stably reach the target speed through the control mode, and stable operation of the vehicle is ensured.

Description

technical field [0001] The invention relates to a vehicle constant speed running control method and a control device. Background technique [0002] With the development of electronic and control technologies in various systems of vehicles, the demand for constant speed driving control of vehicles is increasing day by day. Unnecessary vehicle speed changes can be reduced through the use of vehicle constant speed control, which can effectively save fuel and reduce emission pollution, and improve the efficiency of the engine; in addition, it can reduce the driver's manipulation intensity and improve driving comfort and safety. [0003] Based on the above realities, similar devices or methods have been developed in the prior art. For example, the constant-speed cruising method and device of an electric vehicle with the publication number CN104828084A, by calculating the required cruising speed, and outputting a corrected cruising speed command to the motor controller according ...
