Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] The segmented 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.

[0031] 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.

[0032] The control method is loaded in a hardware contro...

Abstract

The invention relates to a sectional-type vehicle constant-speed travelling control method. A speed lower threshold value is defined, and the speed lower threshold value is smaller than or equal to aset target speed; the actual speed of a vehicle is detected, and when the actual speed of the vehicle is smaller than the speed lower threshold value, the opening of an accelerator is controlled to bethe sum of an initial accelerator opening value and a calculated accelerator opening compensation value; and the accelerator opening compensation value is proportional to a speed error value, and thespeed error value is a difference value between the actual speed of the vehicle and the set target speed. The closer the speed is to the speed lower threshold value, the slower the speed change is, stable operation of the vehicle is guaranteed, the problem that a poor taking feeling is brought to a passenger due to excessive acceleration is solved, a comfortable taking environment is brought to the passenger, and humanized control is achieved.

Description

technical field [0001] The invention relates to a method for controlling constant speed running of a segmented vehicle. 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 accordin...
