Embodiment 1

[0026] The present invention designs a standard starting curve for vehicle starting. The curve is based on different vehicle models and establishes an objective function with time and acceleration as variables, with the minimum fuel volume and optimal comfort as the goal, and the final determined time The relationship between acceleration and acceleration.

[0027] Based on the design of the above-mentioned standard starting curve, a kind of vehicle starting control method of the present invention, such as figure 1 shown, including the following steps:

[0028] Firstly, detect the start signal of the vehicle, and judge whether the start signal is valid, that is, whether the start trigger signal is valid, and whether the vehicle ignition signal is valid. If the starting trigger signal is invalid, and / or the vehicle ignition signal is wireless, it is determined that the starting signal is invalid, and this control ends. If the starting trigger signal is valid and the ignition ...

Embodiment 2

[0033] Based on the standard starting curve designed in Embodiment 1, the present invention also proposes a vehicle starting system, including a vehicle controller, and an obstacle detection system and a motor control and drive system respectively connected to the vehicle controller. The device is also respectively connected with the control button and the ignition signal detection device for collecting the starting trigger signal of the control button and the automobile ignition signal sent by the ignition signal detection device. The vehicle controller judges whether the start signal is valid according to the valid conditions of the start trigger signal and the vehicle ignition signal. The vehicle controller receives the information sent by the obstacle detection system that there are obstacles in the driving direction of the vehicle. If there is no obstacle, or there is an obstacle but there is no risk of collision, the vehicle controller sends a control command to the motor...

Abstract

The invention relates to a vehicle starting control method and a vehicle starting system. When activation of a signal is valid, whether an obstacle exists or not in the vehicle driving direction is detected; under an obstacle-free condition, or an obstacle exists yet no collision danger exists, the vehicle is controlled to be started according to a set standard starting curve; in the mode that starting is conducted according to the standard starting curve, starting control over smooth driving can be promoted; high-comfort, convenient and intelligent driving control functions are achieved, andthe purposes of maximizing the fuel saving amount and improving fuel saving are achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to a vehicle starting control method and a vehicle starting system. Background technique [0002] Today, with the rapid development of the automobile industry, the scale of automobile consumption is huge, and people's requirements for the ride comfort and stability of vehicles are also getting higher and higher. At the same time, the auxiliary driving function is more and more widely used in vehicles. For new energy buses, more electronic and electrical controller systems are used in the whole vehicle, which has a natural control foundation; Higher requirements and expectations; comfort and convenience as well as intelligence are also important aspects. [0003] In the prior art, the starting of most vehicles is controlled by the driver, which has the problems of high vehicle energy consumption, unstable vehicle acceleration, and low comfort when starting...
