The pressure sensor outputs a signal to the PLC controller, when the grip strength reaches or exceeds a system trigger threshold value, the PLC controller outputs a signal for stopping acceleration to the ECU, and the ECU cuts off fuel supply of the engine.
Before the automobile is ignited for use, a pressure set value can be set through a pressure sensor embedded in a steering wheel, a system trigger threshold value is set through a maximum grip strength setting knob on the steering wheel, and the grip strength of a driver under the normal driving condition is about 40N and the grip strength of the driver under the emergency condition is about 120N according to a plurality of groups of data measured by an electronic grip strength meter and relevant documents, so that the default trigger threshold value of the system is set to be 120N. That is, the auxiliary brake control system is activated when the driver's grip on the steering wheel is greater than or equal to 120N. In addition, the size of the system trigger threshold can be adjusted and set through a knob, and the setting range is 50N to 500N.
When the automobile is in an ignition state and meets an emergency, a driver senses that danger is about to occur, can tightly hold the steering wheel with hands, when the signal is equal to or exceeds a system trigger threshold value, a pressure sensor sends a signal to a PLC (programmable logic controller), the PLC sends an emergency braking signal to an ABS (anti-lock brake system), the ABS braking system executes braking action, and the PLC stops sending the braking signal until the driver loosens the steering wheel.

The drawings in the specification of the present invention are briefly described as follows:
FIG. 1 is a schematic diagram of a brake control system of an automobile.
Fig. 2 is a schematic view of a steering wheel in-line pressure sensor.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
as shown in fig. 1, a brake pedal, an accelerator pedal and a steering wheel are arranged in an automobile brake control system, the brake pedal is connected with a booster, the booster is connected with a brake master cylinder, the brake master cylinder is connected with a brake pressure adjusting device, and the pressure adjusting device outputs a brake signal to an ABS brake system, thereby forming a conventional brake system.
The accelerator pedal is provided with a position sensor for sensing the position of the pedal, the position sensor outputs a signal to the ECU, and the ECU outputs a driving signal to the motor for driving the throttle valve, so that a traditional accelerator control system is formed.
The utility model discloses having the pressure sensor who gathers the dynamics of holding in the steering wheel is embedded, being equipped with the biggest grip on the steering wheel and setting up the knob, pressure sensor output pressure signal to PLC controller, set up the system trigger threshold value through rotatory biggest grip, according to multiunit data table 1 that the electron grip gaugember records and combine relevant literature to reachs, the grip of driver under the normal driving condition is about 40N, and the grip under emergency is about 120N, therefore triggers the threshold value to establish the acquiescence of system to 120N. That is, the auxiliary brake control system is activated when the driver's grip on the steering wheel is greater than or equal to 120N. In addition, the size of the system trigger threshold can be adjusted and set through a knob, and the setting range is 50N to 500N.
