Problems solved by technology

[0003] However, when the vehicle starts and stops under the D gear / R gear, it often causes the vehicle to nod (that is, the phenomenon that the front of the vehicle sinks and the rear of the vehicle lifts) and the phenomenon of head-up (that is, the phenomenon that the front of the vehicle tilts and the rear of the vehicle lifts) due to the large acceleration. sinking phenomenon)

Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing.

[0038] When the vehicle starts and brakes in the D gear\R gear, the attitude of the vehicle will often change greatly due to the large acceleration, for example, the vehicle will appear to look up (see Figure 5 ) and nodding (see Image 6 ), whether it is raising the head or nodding, it will bring poor experience and comfort to the passengers, and even endanger the safety of the passengers and vehicles in severe cases.

[0039] Such as Figure 8 As shown, in order to have better start-stop comfort, this embodiment proposes a vehicle start-stop acceleration control method on flat roads, including the following steps:

[0040] Determine the target acceleration value for the vehicle to start and stop on flat roads;

[0041] and adjusting the force output by the engine and the force output by the braking system in response to the target acceleration value, so as to control ...

Abstract

The invention discloses a vehicle start-stop acceleration control method, system and vehicle, comprising the following steps: determining a target acceleration value for the vehicle to start and stop on a flat road; and adjusting engine output force and braking in response to the target acceleration value. The force output by the dynamic system controls the acceleration of the start and stop of the vehicle to be close to the target acceleration value. The invention not only ensures the comfort of driving, but also has good driving experience.

Description

technical field [0001] The invention belongs to the technical field of vehicle start-stop control, and in particular relates to a vehicle start-stop acceleration control method, system and vehicle on flat roads. Background technique [0002] With the continuous improvement of people's living standards and the continuous advancement of science and technology, vehicles have become an indispensable tool in modern people's lives, and are getting closer and closer to people's lives. With the improvement of people's demand for quality of life, the requirements for vehicle comfort are also getting higher and higher. [0003] However, when the vehicle starts and stops under the D gear / R gear, it often causes the vehicle to nod (that is, the phenomenon of sinking the front of the vehicle and the phenomenon of the rear of the vehicle) and the phenomenon of raising the head (that is, the phenomenon of tilting the front of the vehicle and the phenomenon of the rear of the vehicle) due t...
