Abstract

The invention provides a footbrake error step-on-accelerator removing device comprising the following connected units: a given value storage unit, an accelerator signal value input unit, an accelerator signal value change rate calculation unit, a calculation value storage unit, a comparing unit and an output unit, wherein the given value storage unit gives an accelerator signal value change rate; the calculation value storage unit is used for storing the calculated accelerator signal value change rate; the comparing unit compares the calculated accelerator signal value change rate with the given accelerator signal value change rate; and the output unit is used for outputting an input accelerator signal if the calculated accelerator signal value change rate is less than the given accelerator signal value change rate, and outputting a result that an accelerator signal is zero if the calculated accelerator signal value change rate is more than or equal to the given accelerator signal value change rate. The footbrake error step-on-accelerator removing device provided by the invention can carry out sampling calculation on an accelerator signal value according to time variation, calculates the accelerator signal value change rate, normally outputs the accelerator signal value when the accelerator signal value change rate is small, and outputs the result that the accelerator signal is zero when the accelerator signal value change rate is large, namely an error step-on-accelerator state. The method provided by the invention can remove accelerator control in time after an accelerator is inaccurately stepped in a foot braking process.

Description

technical field [0001] The invention relates to a method and a device for controlling safe driving of an automobile, in particular to a method and a device for releasing a foot brake from accidentally stepping on an accelerator. Background technique [0002] The accelerator and foot brake of the car are placed side by side on the right side of the driver's seat in the cab, and are controlled separately by the driver's right foot through transposition. When the car is running normally, the driver steps on the accelerator, and the accelerator signal value can be transmitted through the accelerator wiring harness. Control the speed of the vehicle, the accelerator signal value is a variable that changes with time, the car is running at a constant speed, the rate of change of the accelerator signal value is zero, when the car accelerates slowly, the rate of change of the accelerator signal value is small, and when the car accelerates rapidly, the change rate of the accelerator sig...
