Problems solved by technology

[0004] The above-mentioned accelerator pedal error protection scheme is based on the driver’s driving intention to judge whether the driver has misoperation. Due to other reasons, although the driver releases the accelerator pedal, the accelerator signal is incorrectly output due to the pedal being stuck, and timely and effective protection cannot be done.

Embodiment 1

[0031] Embodiment 1: The present invention provides a kind of automobile throttle fault-tolerant safety control method and its device, such as figure 1 and figure 2 As shown, the motor controller serves as the control unit to receive the signal transmitted by the sensor unit, and controls the accelerator signal in real time; the resistive film pressure sensor is used to detect whether the accelerator pedal is under pressure, so as to judge whether the driver is stepping on the pedal; the output signal of the sensor unit is detected in real time , the accelerator pedal signal, and the accelerator pedal lock signal determine the output state of the accelerator pedal and control the output of the accelerator pedal.

[0032] The sensor unit is installed on the accelerator pedal. The sensor unit adopts a resistive film pressure sensor. When the accelerator pedal is stepped on, the resistance value of the resistive film pressure sensor will change with the change of pressure; conne...

Embodiment 2

[0033] Embodiment 2: the present invention also provides a kind of automobile throttle fault-tolerant safety control method and its device, such as figure 2 and image 3As shown, the integrated control module is used as the control unit to receive the signal transmitted by the sensor unit and control the accelerator signal in real time; the resistive film pressure sensor is used to detect whether the accelerator pedal is under pressure, so as to judge whether the driver is stepping on the pedal; through the output signal of the sensor unit Process and compare with the set reference signal to control the output of the accelerator pedal signal; install this external sensor module and integrated control module on the accelerator pedal, the sensor module uses a resistive film pressure sensor, and the resistive film pressure when the accelerator pedal is stepped on The resistance value of the sensor will change with the change of pressure. The signal output by the sensor unit is p...

Abstract

The invention relates to an automobile accelerator fault-tolerant security control method and device. The method comprises the following steps that S1, a sensor unit detects pressure on a pedal; S2, the sensor converts the pressure on the accelerator pedal into electric signals to be output to a control unit; S3, the control unit judges whether or not a driver stamps on the pedal according to thesignals; S4, if it is determined that pressure exists on the pedal, signals of the accelerator pedal are output, and the control unit re-judges whether or not signals of a pedal lock are output normally; S5, if the signals of the pedal lock are output normally, signals of the accelerator pedal are output normally, if the signals of the pedal lock are output abnormally, the signals of the accelerator pedal are output abnormally, and output is stopped. According to the method and device, timely and effective protection can be performed when signals of the accelerator pedal and signals of accelerator pedal lock are output by mistake due to the fact that a driver loosens the accelerator pedal and the pedal is locked by mistaken external stress of the accelerator pedal, the installing mode is simple and diversified, and the device is easy to control and obtain.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a vehicle accelerator fault-tolerant safety control method and a device thereof. Background technique [0002] With the rapid development of new energy technology, electric vehicles have gradually become the main means of transportation. The safety of vehicle functions needs to be guaranteed. The accelerator pedal is particularly important for the source of vehicle output power control. For the protection of the accelerator pedal, the existing technology is a protection scheme for realizing the accidental stepping on the accelerator pedal and the brake, such as the patent "A method and protection device for identifying the wrong stepping on the accelerator of a car" (application number: 201610065108.8, application date: 2016-01-23) The mentioned time is based on the time taken by the driver from releasing the brake to stepping on the accelerator. There is a significan...
