After corresponding position signals of the gear operating lever obtained by a gear operating lever for changing a driving state by movement among a forward speed gear, a neutral gear, a reverse gear and a parking gear, and position sensing devices among positions matched with the gear operating lever are logically operated and judged, the corresponding gear signals consistent to the normal position signals are outputted to a gear operating mechanism, and gear signals inconsistent to an effective position signal, or gear disturbance signals are preferentially and forcibly outputted to the gear operating mechanism and converted into control signals of the neutral gear. Under the condition that a part or all of the position sensing devices of the gear operating lever are failed, the method can be maintained in the effective state of neutral gear output by multiple elements and precedence in order to ensure the purpose of safe drive.
Description
Technical field
What the present invention relates to is a kind of method that the position signal of gear operating lever is discerned and controlled of being used for, under the situation that the gear operating lever position transducer partly or entirely lost efficacy, can be with polynary and made vehicle remain the effective status of neutral gear output, to guarantee the purpose of driving safety by preferential mode.
Background technique
The self-shifting vehicle in the process of moving, the conversion of its gear generally can be by automatically, or can be exchanged into manual mode and control.Under automatic control state, in case speed change is handled sensed system and is gone wrong, for example under the part or all of situation about losing efficacy of the position transducer of gear operating lever, can put signal to output error of gear control/actuator even dangerous gear, with the serious threat traveling security.
That publication number is that the Chinese patent literature of CN1284451A discloses is a kind of " can automatically and the transmission control unit of hand shift ", wherein described all places of gear operating lever and the function of expression, but the identification of this position of function is the independent identification of being undertaken by the sensor that is separately positioned on these positions.Close therewith technology also has disclosed in documents such as German patent DE-A-19905627.
Publication number is the Chinese patent literature of CN1434906A, a kind of " be used for can manually or the control unit of the automotive transmission of automaitc shfit " be disclosed, wherein the location recognition of gear operating lever has been adopted and be called as two different sensing elements of first and second length, employed gear operating lever can have the motion of two different direction: switch between two sensing elements when the gear operating lever horizontal motion, to distinguish the operating pattern of automatic and manual shift; When on vertical with it direction, moving, to determine the gear positions under each self mode.But can find in Fig. 2 a～2g content by the document, the manual control downshift position that is used for the process of advancing shown in the neutral position shown in its Fig. 2 b and Fig. 2 g, the output state relation of its position sensing is identical; In the output relation shown in Figure 5 of the document, also the output relation with its reverse gear is also identical simultaneously for this output relation.According to general general knowledge in the automotive field, the relation between the position of gear operating lever and gear are arranged can not be changed.If therefore identical output relation has been represented neutral gear simultaneously and retreated shelves and two different direction of travel of forward gears,, will be very dangerous for the manipulation and the control of actual travel process gear.In the document, though similarly gear operating lever is in the situation that different actuated position has identical output state and also has many places.For avoiding the appearance of this phenomenon, adopted its alleged " pedal " COMM communication in the document to distinguish.According to the present mankind's technical capability,, only hinge on that a kind of TURP changes switch or sensor obviously is insecure with the important device of driving of this relation and life safety.In case diverter switch promptly can turn back to above-mentioned conflicting control result after losing efficacy equally.
In addition, also there is unsafe factor in the document to the position sensing of Parking shelves " P " and forward gears " D ", when three sensors are output as identical low level " 0 ", will produce the signal of forcing Parking shelves " P " that is:; When three sensors are output as identical high level " 1 ", will produce the signal of forward gears " D ".And according to the general general knowledge of person in electronics, when the power supply of arbitrary part in wherein sensor, control wiring or the controller short circuit appears or situation about opening circuit under, the capital produces one of above-mentioned same output result, and all might cause a kind of catastrophic consequence to the automobile that is under the travelling state.Also increased the Fault Identification mode in the document for this reason, but its identification has narrow limitation on the one hand, for example under the automatic gear-shifting pattern, can not discern power supply short circuit or when opening circuit three sensors simultaneously for the situation of " 1 " or " 0 " etc., the result of its identification fault also only is limited as the warning signal of a kind of sound, light on the other hand, for automatic control system and driver, the effective measures that can't take to make the vehicle in travelling to get back to the neutral gear safe condition.
