The purpose of the utility model can realize through following technical proposal: the device of eliminating shift impact in a kind of automobile; Comprise the oil sprayer on ECU, clutch pedal and the motor in the automobile; It is characterized in that; This device comprise one be arranged on clutch pedal the place and can detect the detection unit of clutch pedal position; Described detection unit links to each other with ECU and can the position information of detected clutch pedal be converted to electrical signal transfer and gives ECU, and described ECU can handle and send to oil sprayer the control signal that reduces fuel injection pulsewidth to the electrical signal that transports.
The working principle of this device is following: when the driver prepares to shift gears; Step on down clutch pedal, the position of detection clutch pedal is after clutch pedal is moved downward to predefined value; Detection unit sends electrical signal to ECU; ECU receives the back this electrical signal is handled, and sends control signal to oil sprayer, and oil sprayer reduces fuel injection quantity after receiving the signal of the minimizing fuel injection pulsewidth that ECU sends; Thereby make motor reduce the moment of torsion of output, the change amount of the moment of torsion of motor just diminishes when shifting gears like this.This device is through revising at the fuel injection pulsewidth of stepping on this state of clutch gear-shift under, thereby rationally reduces the output torque of motor in clutch disengage process, makes when gearshift because " towering car " phenomenon elimination that engine load reduces suddenly to cause.
In above-mentioned a kind of automobile, eliminate in the device of shift impact; Described detection unit comprises the displacement transducer that is arranged on the clutch pedal place; Described displacement transducer is connected on the car body; And this displacement transducer can send electrical signal to ECU when described clutch pedal is moved downward to the preset, and ECU can send the control signal that once reduces fuel injection pulsewidth according to the electrical signal that transports to oil sprayer.After clutch pedal arrived the preset, the oil sprayer minimizing oil spout that will begin in a minute changed so more directly and is convenient to and controls.
In above-mentioned a kind of automobile, eliminate in the device of shift impact; As another kind of scheme; Described detection unit comprises the displacement transducer that is arranged on the clutch pedal place; Described displacement transducer is installed on the car body, and this displacement transducer can detect the displacement amount that clutch pedal moves down and convert electrical signal to issues ECU, and ECU can send the control signal that repeatedly reduces fuel injection pulsewidth according to the electrical signal that transports to oil sprayer.After clutch pedal moved down through the preset, displacement transducer was started working, and sent induced signal to what ECU continued, and the oil sprayer that makes that ECU slowly continues reduces fuel injection quantity, controls more accurate like this.
In above-mentioned a kind of automobile, eliminate in the device of shift impact, described displacement transducer is an infrared sensor.Infrared sensor adopts contactless induction, long more also not wearing and tearing service time.
In above-mentioned a kind of automobile, eliminate in the device of shift impact, described displacement transducer is an inductive displacement transducer.
Compared with prior art; This device is through revising at the fuel injection pulsewidth of stepping under this state of clutch gear-shift; Thereby rationally reduce the output torque of motor in clutch disengage process, make " alarmming car " phenomenon that when gearshift, reduces suddenly to cause eliminate owing to engine load.Infrared sensor adopts contactless induction, long more also not wearing and tearing service time.
