Problems solved by technology

It can be seen that the driver has to perform different operations according to the degree of urgency of stepping on the brakes. If the automatic transmission does not perform different shift schedules when the urgency of braking is different, it will increase the risk of driving.

Embodiment Construction

[0011] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0012] Such as figure 1 Shown is the structural diagram of the device capable of judging the emergency degree of braking of the present invention. The device includes a pair of position sensors 1 , a brake pedal 2 , a micro control unit 3 (English full name: Micro Control Unit; English abbreviation: MCU) and an automatic transmission 4 . The brake pedal 2 has four positions A, B, C and D. Position A represents the natural position of the brake pedal 2 when the brake pedal 2 is not stepped on; position B represents the activation position of the brake light switch, that is, the brake light is activated when the brake pedal 2 is lower than position B, and the brake pedal 2 When it is higher than position B, the brake light is turned off; position C represents the balance position between braking force and slope resistance, tha...

Abstract

The invention relates to a device for judging the brake degree, which comprises a brake pedal, a dual-position sensor, a micro unit and an automatic speed transformer. Wherein, said dual-position sensor is mounted on the brake pedal, to sense its positions and transmit the signals of at least two special positions of brake pedal to the micro controller; said micro controller according to the time difference that receiving the position signals judges the brake degrees, to shift the automatic speed transformer. The invention also discloses a relative method. And it has the advantages that it can improve the driving safety.

Description

technical field [0001] The invention relates to a device and method capable of judging the emergency degree of braking, in particular to a device and method capable of judging the emergency degree of braking of a vehicle equipped with an automatic transmission. Background technique [0002] When a vehicle equipped with an automatic transmission is running, if the vehicle decelerates normally, the driver will slowly step on the brakes, and when the vehicle speed drops to a certain value (the automatic transmission system shifts gears according to parameters such as vehicle speed, throttle, acceleration, etc.), the The vehicle described above will downshift. When the driver brakes suddenly, the shifting schedule is required to be different from the regular deceleration of the vehicle. At this time, when the driver steps on the brakes, the accelerator should be loosened to the bottom to reduce the engine speed of the vehicle, and the clutch cannot be disengaged, and the transm...
