Embodiment 1

[0025] This embodiment is an implementation of an active braking force distribution control system that directly measures tire pressure.

[0026] The implementation steps of this embodiment are:

[0027] The first step is to accurately detect the air pressure in all tires. In this embodiment, a direct measurement method is used to measure the tire pressure, and the accuracy of the tire pressure sensor can reach 0.01 bar. Use the pressure sensor 100 with a transmitter to transmit the pressure of each tire to the receiver 200 by radio, and the receiver will hand over the tire pressure to the active braking force distribution control system controller 500 for processing;

[0028] The second step is that the controller 500 of the active braking force distribution control system analyzes the detected pressure value, compares it with the pre-given normal pressure value, and determines whether the pressure of each tire is normal;

[0029] The third step is that the active braking fo...

Embodiment 2

[0034] This embodiment is an implementation of an active braking force distribution control system that indirectly measures tire pressure.

[0035] The first step is that this embodiment adopts the indirect measurement method to measure the tire pressure. In the indirect measurement method, the pressure in the tire is estimated by measuring the tire speed, the height of the chassis from the ground, or the temperature of the tire. The active braking force distribution control system controls The processor 500 performs processing according to the estimated value of the tire internal pressure;

[0036] The second step is that the controller 500 of the active braking force distribution control system analyzes the detected pressure value, compares it with the pre-given normal pressure value, and determines whether the pressure of each tire is normal;

[0037] The third step is that the active braking force distribution control system controller 500 takes necessary safety measures f...

Abstract

The invention discloses an active braking force distribution and control system with a tire pressure monitoring function. The system comprises a tire pressure sensor (100), a wireless receiver (200), an active braking force distribution and control system controller (500) with the tire pressure monitoring function, a braking pressure adjuster (600) and a multichannel braking pressure control module, wherein the tire pressure sensor transmits detected tire pressure to the wireless receiver; the receiver sends a tire pressure signal to the braking force distribution and control system controller; the controller analyzes pressure conditions of tires, processes different situations and controls the braking pressure adjuster through the multichannel braking pressure control module respectively to adjust the braking forces of all wheels to optimal values according to required total braking force distribution, so a vehicle can keep moving forward stably and deaccelerate slowly; meanwhile, the braking force distribution and control system controller communicates with an engine controller (800) to require to reduce an output torque, so the vehicle deaccelerates slowly or stops. The active braking force distribution and control system is applicable to various automobiles.

Description

[0001] technical field [0002] The invention relates to an automobile active braking force distribution control system with tire pressure monitoring, belonging to the technical field of automobile safety. Background technique [0003] Whether the pressure of the car tire is normal directly affects the fuel consumption, emission and the life of the tire itself. More importantly, the sudden rupture and air leakage of automobile tires may suddenly change the running direction of the automobile and cause traffic accidents, causing property damage in light cases, casualties and road blockage in severe cases. Therefore, the application of tire pressure monitoring system (TPMS) has gradually become popular. [0004] However, most of the current TPMS applications are limited to automatic pressure warnings. These systems can only help drivers measure tire pressure. Drivers usually don’t have to worry about tire pressure and rely on TPMS to report it. There is no active protection ...
