Abstract
The invention relates to a backup light controlling method. The method includes that a position signal of a hand lever of an automatic gearbox is collected by a gear sensor in real time; whether the hand lever passes an R-gear or not is judged; when the hand lever of the an automatic gearbox passes the R-gear, an internal switch S0 of an R-gear sensor is closed, a control signal is given by a TCU (terminal control unit) of an automatic gearbox so as to disconnect a normally closed switch S1; at the same time, whether stopping time T of a gear shifting hand lever at the R-gear is larger than a threshold T0 or not is judged by the TCU of the automatic gearbox, if the stopping time T is smaller than the threshold T0, a control signal is given by the TCU of the automatic gearbox to keep the normally closed switch S1 in disconnection, and the backup light does not emit light; when the stopping time T is larger than the threshold T0, a control signal is given by the TCU of the automatic gearbox to enable the normally closed switch S1 to recover the normally closed state, and the backup light emits light; when the hand lever of the automatic gearbox does not pass the R-gear, the internal switch S0 of an R-gear sensor is disconnected, the normally closed switch S1 is closed, and the backup light does not emit light. The backup light controlling method is good in adaptability and wide in application range, and the backup light does not flash during the gear shifting process, so that driving safety is improved.
Description
Technical field
The present invention relates to the automotive automation field, particularly relate to a kind of control method of reversing automobile lamp.
Background technology
At present, automatic gearbox has become a kind of developing direction of Modern Car configuration, and in automatic gearbox, when gear shifting handle placed the R shelves, R shelves gear position sensor internal circuit was controlled backing-up lamp, makes backing-up lamp bright.Yet pushed by the P shelves in the process of N shelves or D shelves at gear shifting handle, owing to can pass through the R P PARK Position P, the backing-up lamp circuit can be connected in moment, caused backing-up lamp to glimmer, and was unfavorable for safe driving.
Summary of the invention
The objective of the invention is to overcome the weak point that exists in the above-mentioned technology, provide a kind of simple in structure, reasonable in design, can effectively avoid the backing-up lamp flicker, improve the backing-up lamp control method of drive safety.In order to achieve the above object, the technical scheme that the present invention adopts is: described method comprises: shift sensor is gathered the position signal of automatic transmission with hydraulic torque converter handle in real time, and judges whether the retaining through R, when through the R retaining, and R retaining shift sensor internal switch S
0Closure, Automatic Transmission control unit TCU provides control signal, makes normally closed switch S
1Break off, Automatic Transmission control unit TCU judges that whether dwell time T that shift handle keeps off at R is greater than threshold value T simultaneously
0, when dwell time T less than threshold value T
0The time, Automatic Transmission control unit TCU provides control signal, makes normally closed switch S
1Keep off-state, backing-up lamp does not work, when dwell time T greater than threshold value T
0The time, Automatic Transmission control unit TCU provides control signal, normally closed switch S
1Recover normally off, backing-up lamp is bright, when not through the R retaining, and R retaining shift sensor internal switch S
0Break off normally closed switch S
1Closure, backing-up lamp does not work.Advantage of the present invention is: simple in structure, reasonable in design, reduce manufacture difficulty and cost, and owing to do not need complicated peripheral circuit and system, comformability is good, applied range, gearshift procedure backing-up lamp flicker free improves drive safety.
Description of drawingsFig. 1 is a control method diagram of circuit of the present invention; Fig. 2 is an electric system schematic diagram of the present invention.
The specific embodimentBelow in conjunction with accompanying drawing embodiments of the invention are described in further detail.Can be known that by Fig. 1-Fig. 2 method of the present invention comprises: shift sensor is gathered the position signal of automatic transmission with hydraulic torque converter handle in real time, and judges whether the retaining through R, when through the R retaining, and R retaining shift sensor internal switch S
0Closure, Automatic Transmission control unit TCU provides control signal, makes normally closed switch S
1Break off, Automatic Transmission control unit TCU judges that whether dwell time T that shift handle keeps off at R is greater than threshold value T simultaneously
0, when dwell time T less than threshold value T
0The time, Automatic Transmission control unit TCU provides control signal, makes normally closed switch S
1Keep off-state, backing-up lamp does not work, when dwell time T greater than threshold value T
0The time, Automatic Transmission control unit TCU provides control signal, normally closed switch S
1Recover normally off, backing-up lamp is bright, when not through the R retaining, and R retaining shift sensor internal switch S
0Break off normally closed switch S
1Closure, backing-up lamp does not work.S1 one end and R retaining shift sensor internal switch S are closed in described make and break
0Join, the other end and backing-up lamp join.Described Automatic Transmission control unit TCU is through relay and normally closed switch S
1Link to each other, relay receives the control signal that Automatic Transmission control unit TCU provides, and drives normally closed switch S1 disconnection or closed.Electric system principle of the present invention is as shown in Figure 1, R shelves gear position sensor internal switch S
0With normally closed switch S1 jointly as the control element of backing-up lamp 2, normally closed switch S
1Be connected on R shelves gear position sensor internal switch S
0And between the backing-up lamp 2, R shelves gear position sensor internal switch S
0Be arranged in the gear position sensor 4 of automatic transmission with hydraulic torque converter, Automatic Transmission control unit TCU receives R shelves gear position sensor internal switch S in the gear position sensor 4
0Signal, and through control relay 3 control normally closed switch S
1State, power supply 1 provides power supply for gear position sensor 4 and relay 3.Control method diagram of circuit of the present invention is as shown in Figure 2, and when gearshift, shift sensor is gathered the position signal of automatic transmission with hydraulic torque converter handle in real time, and judges whether the retaining through R, if without the R retaining, and R retaining shift sensor internal switch S
0Be in off-state, Automatic Transmission control unit TCU does not send instruction yet and gives relay 3, normally closed switch S
1Be kept closed.When through the R retaining, R retaining shift sensor internal switch S
0Closure, this moment, Automatic Transmission control unit TCU at first made normally closed switch S
1Break off, then through Automatic Transmission control unit TCU judge handle at the dwell time T of R retaining whether greater than threshold value T0, judge that promptly shift handle is to continue to get into the R retaining (in the resident time T of R retaining greater than threshold values T necessarily
0) still handle put (in the resident time T of R retaining less than certain threshold values T through the R gear
0).When dwell time T less than threshold value T
0The time, Automatic Transmission control unit TCU provides control signal, makes normally closed switch S
1Break off, backing-up lamp does not work, and prevents the backing-up lamp flicker; When dwell time T greater than threshold value T
0The time, normally closed switch S
1Remain closed, backing-up lamp is bright.When TCU lost efficacy, because normally closed switch S
1Keep the normally closed state that closes, still can keep off shift sensor internal switch S by R
0The control backing-up lamp is lighted, and promptly returns to the mode of general backing-up lamp.
