Abstract
The present disclosure discloses a terrain based dynamic gear shift control method and system for a vehicle. The method includes: during running of a vehicle, obtaining a current terrain; according to the current terrain, the economic gear shift strategy, and the dynamic gear shift strategy, generating a current gear shift strategy curve; and according to the current gear shift strategy curve, controlling a transmission to perform gear shift. The present disclosure can make the vehicle have wider adaptability, and achieve a better dynamic balance between economy and dynamic performance.
Claims10
A terrain based dynamic gear shift control method for a vehicle, comprising:
- presetting an economic gear shift strategy and a dynamic gear shift strategy, and further comprising the following steps:
- step 1):
- during running of the vehicle, acquiring current terrain information of the vehicle by an electronic horizon system;
- step 2):
- performing, by a gear shift controller, dynamic interpolation fusion according to the current terrain information, the economic gear shift strategy, and the dynamic gear shift strategy, to generate a current gear shift strategy curve;
- and
- step 3):
- controlling, by the gear shift controller according to the current gear shift strategy curve, a transmission to perform gear shift.
A terrain based dynamic gear shift control system for a vehicle, comprising:
- a gear shift controller in which an economic gear shift strategy and a dynamic gear shift strategy are preset;
- a transmission;
- and
- an electronic horizon module configured to, during running of the vehicle, acquire current terrain information of the vehicle, wherein the gear shift controller performs dynamic interpolation fusion according to the current terrain information, the economic gear shift strategy, and the dynamic gear shift strategy, to generate a current gear shift strategy curve, and controls, according to the current gear shift strategy curve, the transmission to perform gear shift.
