Problems solved by technology

The general basic control methods are set based on the parameters of the vehicle's stable driving conditions, or based on the parameters of the dynamic process. They do not fully consider the driver's human factors and the influence of the vehicle's driving environment factors. When the car driving environment factors appear, it will affect the control of the transmission and the driving state of the car, thus affecting the comfort of the ride.

Embodiment Construction

[0033] Such as figure 1 The working modes of the shown car basic control method include: stop / start mode, CVT basic control mode, engine rev mode and limp home mode, with the following basic control methods:

[0034] a) When the vehicle is in the stop / start mode, when the ignition device is turned on and the control relay is turned on, the vehicle enters the CVT basic control mode from the stop / start mode.

[0035] b) When the vehicle is in the CVT basic control mode, turn off the ignition device, and enter the stop / start mode from the CVT basic control mode.

[0036] c) When the engine speed of the vehicle is NE≤300rpm, enter the engine rotation mode from the CVT basic control mode.

[0037] d) When the engine speed of the vehicle is NE>300rpm, enter the CVT basic control mode from the engine rotation mode.

[0038] e) When the vehicle is in the CVT basic control mode, when only the control relay is closed, the CVT basic control mode enters the limp home mode.

[0039] f) ...

Abstract

The invention discloses a method for controlling an automobile equipped with a CVT and the method fully considers the influence of the anthropogenic factors of drivers and the automobile driving environment. The technical scheme is as follows: the method for controlling an automobile equipped with a CVT comprises a basic controlling method for an automobile and a controlling method used when an automobile is in a moving state; the working mode of the basic controlling method comprises a stopping and starting mode, a CVT basic controlling mode, a motor driving mode and a limping back home mode; the working mode of a controlling method used when an automobile is in a moving state comprises a travel reduction mode, a constant speed mode and an acceleration driving mode. The invention controls the CVT according to the anthropogenic factors of drivers, the automobile driving environment and the corresponding controlling strategy, which allows the CTV to realize intelligent controlling, prolongs the service life of part, reduces unnecessary compact, saves fuels, and enhances traveling comfort.

Description

technical field [0001] The present invention relates to a basic control method of a car, in particular to a basic control method of a car equipped with a CVT. Background technique [0002] Conventionally, a continuously variable transmission (also referred to as "CVT") has been widely used as an automatic transmission for motor vehicles and the like due to its excellent stability. CVT Since the transmission ratio changes continuously, cars using CVT often use automatically controlled continuously variable gear shifting. Therefore, in general vehicles using continuously variable transmissions, the basic control method of automobiles is the key technology for controlling continuously variable transmissions. The general basic control methods are set based on the parameters of the vehicle's stable driving conditions, or based on the parameters of the dynamic process. They do not fully consider the driver's human factors and the influence of the vehicle's driving environment fact...
