Problems solved by technology

[0006] (2) The service life of friction parts is shortened:
When the engine is started again, there will be dry friction or semi-dry friction between the cylinder and the piston, which will accelerate the wear of parts, and once the starting resistance increases greatly, it will cause difficulty in starting.
[0008] (3) Decreased battery capacity and shortened life:
[0011] The longer the car is parked, the more difficult it is for the tire to recover from the deformation of the part that touches the ground, resulting in unbalanced tires Once t

Abstract

The invention relates to the field of vehicle control, and provides a vehicle control method and system. The vehicle control method comprises the steps of transmitting a maintenance and operation instruction to a T-BOX on a telematics remote service provider TSP; receiving vehicle state information returned in response to the maintenance and operation instruction from the T-BOX, wherein the vehicle state information comprises engine stopping time; when the engine stopping time exceeds a first preset value, transmitting a starting instruction to the T-BOX. By means of the vehicle control methodand system, through the vehicle telematics service provider TSP, the maintenance and operation instruction is conveyed to control the vehicle T-BOX, and remote control of a vehicle is achieved; whenthe engine stopping time exceeds the first preset value, the starting instruction is conveyed to the T-BOX, and periodic starting maintenance of the vehicle is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle control method and system. Background technique [0002] Nowadays, many car owners leave their cars in the parking lot for a long time for reasons such as saving money or long-term business trips. However, the long-term stationary placement of the vehicle is a serious hazard to the vehicle. [0003] If the car is not used for a long time, the possible hazards are as follows: [0004] (1) Deformation, aging, and easy damage of oil seals in various parts: [0005] When the vehicle is stopped, the contact force on the concave circumference of the parking is uniform. The greater the direction of force, the greater the deformation of the parking seal; the longer the vehicle is parked, the harder it is to recover until the permanent deformation of the oil seal occurs. This is where the oil spill begins. [0006] (2) The service life of friction parts is shortened...
