Referring to fig. 1-3, the present invention provides a technical solution: a driving behavior improvement remote control system comprises a whole vehicle control module 1, a remote monitoring module 2, a wireless communication module 3 and a monitoring platform 4, wherein the whole vehicle control module 1 and the remote monitoring module 2 are interactively connected in a CAN communication mode;

the whole vehicle control module 1 comprises an acceleration braking unit 101, an instrument unit 102 and a parameter calibration unit 103;

the remote monitoring module 2 is interactively connected with a monitoring platform 4 through a wireless communication module 3;

the whole vehicle control module 1 comprises three detection parts, namely an acceleration braking unit 101, an instrument unit 102 and a parameter calibration unit 103;

the acceleration braking unit 101 detects the rapid acceleration and rapid deceleration of the whole vehicle, and when the rapid acceleration value A1 of the whole vehicle is greater than a preset threshold value A2, the count value a1+1 is obtained; when the vehicle sudden deceleration value B1 is larger than a preset threshold value B2, counting the value B1+ 1; the meter module 6 detects the speed of the whole vehicle, and when the speed value C1 of the whole vehicle is greater than a preset threshold value C2, the count value C1+1 is obtained; when a1 exceeds the preset alarm threshold a2, the meter unit 102 displays a text alarm "accelerate too fast, please note that the vehicle has limited power"; when b1 exceeds the preset alarm threshold b2, the meter unit 102 displays a text alarm "slow down too fast, please note"; when c1 exceeds the preset alarm threshold c2, the meter unit 102 displays a text alarm "the vehicle speed is too fast, please note that the vehicle is limited"; the parameter calibration unit 103 can recalibrate the vehicle speed V, the acceleration power P and the acceleration torque slope K of the whole vehicle;

the remote monitoring module reads the driving behavior state data a1, b1 and c1 sent by the whole vehicle control module in a CAN communication mode, and issues and recalibrates the whole vehicle control module according to the received new vehicle parameters sent by the monitoring platform.

The wireless communication module sends the driving behavior state data to the monitoring platform in a 3G, 4G, 5G or WIFI network mode, and issues the received new parameter calibration requirement to the remote monitoring module.

The monitoring platform is used for inquiring vehicle operation data A1, B1, C1 and the like, calibrating the vehicle speed V, the acceleration power P and the acceleration torque slope K of the whole vehicle, and issuing calibration content and a request for relevant parameters of the control module of the whole vehicle to the remote monitoring module.
