Description
Technical field
The present invention relates to a kind of automatic gearbox control technique, specially refer to a kind of automatic gearbox two shift control systems.
Background technique
The prior art automatic transmission adopts transmission output shaft to drive transmission oil pump usually, then by the planetary clutch state of oil pressure actuated speed changer that oil pump is exported, reaches the purpose of its speed change.When transmission output speed is higher (when the speed of a motor vehicle is higher), the oil pressure of transmission oil pump output is higher, and the control switch of high speed gear will be opened by system, and system enters high speed gear working state; When transmission output speed is low (when the speed of a motor vehicle is low), the oil pressure of transmission oil pump output is lower, and the control switch of low speed gear will be opened by system, and system enters low speed gear working state.When automobile driving speed close to zero the time, when perhaps just having started from scratch, the oil pressure of the transmission oil pump output that transmission output shaft drives will be close to zero, speed changer itself can not be placed in neutral, forward gear or Parking gear with gear according to the oil pressure variation, the shift handle of reliable manual control speed changer only, drive the mechanical mechanism of a cover, speed changer is placed in needed gear.Therefore, prior art automatic transmission shift handle generally includes four gears such as D gear, N gear, P gear and R gear, and wherein, the D gear is forward gear, and the N gear is neutral, and the P gear is the Parking gear, and the R gear is reverse gear shift.In addition, the prior art automatic transmission adopts automatic transmission computer control unit TCU that the operation of automatic transmission is controlled, comprise shift handle and coordinating that system lights a fire, exercises, for example: only motor could be lighted a fire when shift handle is in N gear or P gear; Must switch to a D gear or R ability of keeping off a car from N gear or P gear after igniting starts; Parking on the slope for a long time must switch to the P gear, otherwise may cause the parking brake load excessive, and vehicle slides from the slope and causes the accident.Although be automatic transmission, practical operation is got up, and still seems numerous and diverse.Obviously, it is more that the prior art automatic transmission control system exists gear, the problems such as trivial operations.
Summary of the invention
More for solving the gear that the prior art automatic transmission control system exists, the problems such as trivial operations, the present invention proposes a kind of automatic gearbox two shift control systems.Automatic gearbox of the present invention two shift control systems comprise automatic transmission computer control unit TCU, automatic transmission, gas pedal, braking pedal, shift handle, automatic transmission output shaft Locking Device, vehicle speed sensor and speed probe; Shift handle is provided with forward gear D gear and reverse gear shift R gear, and inserts the pressure neutral switch of parking in shift handle; TCU is in different working staties according to the SC sigmal control automatic transmission of vehicle speed sensor, speed probe, gas pedal and braking pedal, comprising:
When automobile parking, the TCU perception vehicle speed sensor signal speed of a motor vehicle is close to zero; The loop of braking pedal is in on-state simultaneously, and namely this moment, the driver braked, and TCU controls automatic transmission and throws off gear, enters neutral; When the signals of rotational speed sensor engine speed close to zero, switch-off, TCU controls automatic transmission output shaft Locking Device and enters lockup state, automobile enters parks;
When automobile starting, the loop of TCU perception braking pedal keeps for being communicated with the state of parking, and simultaneously according to signals of rotational speed sensor, if engine speed does not continue the several seconds higher than more than 600rpm, continues to keep the state of parking; When the signals of rotational speed sensor engine speed continues the several seconds higher than 600rpm, the braking pedal loop disconnects, gas pedal is UNICOM, TCU controls automatic transmission output shaft Locking Device and enters opening state, TCU is D gear or R gear according to the shift handle position, controls automatic transmission and hangs into forward gear or reverse gear shift;
When automobile normal running, TCU perception vehicle speed sensor signal is controlled automatic transmission according to the speed of a motor vehicle and is entered low speed or high speed operation state;
When special circumstances need moving vehicle, open the pressure neutral of inserting in the shift handle switch of parking, automatic transmission output shaft Locking Device enters opening state, and automobile enters neutral position state by the state of parking, and vehicle can be pushed or drag.
The useful technique effect of automatic gearbox of the present invention two shift control systems is the gear quantity that has reduced shift handle, has simplified operation.Can not produce misoperation, the system automation degree is higher.And, simple in structure, do not need the prior art automatic transmission control system is done larger change, be easy to realize.
Description of drawings
Accompanying drawing 1 is the structural representation of automatic gearbox of the present invention two shift control systems.
Below in conjunction with the drawings and specific embodiments, automatic gearbox of the present invention two shift control systems are further described.
Embodiment
Accompanying drawing 1 is the structural representation of automatic gearbox of the present invention two shift control systems, in figure, 1 is automatic transmission computer control unit TCU, 2 is automatic transmission, and 3 is gas pedal, and 4 is braking pedal, 5 is shift handle, 6 is automatic transmission output shaft Locking Device, and 7 is vehicle speed sensor, and 8 is speed probe.As seen from the figure, automatic gearbox of the present invention two shift control systems comprise automatic transmission computer control unit TCU, automatic transmission, gas pedal, braking pedal, shift handle, automatic transmission output shaft Locking Device, vehicle speed sensor and speed probe; Shift handle is provided with forward gear D gear and reverse gear shift R gear, and inserts the pressure neutral position switch in shift handle; TCU is in different working staties according to the SC sigmal control automatic transmission of vehicle speed sensor, speed probe, gas pedal, braking pedal and shift handle, comprising:
