2, sensor-based system comprehensive segmentation sensing circuit Anti-bumping protection state is checked successively:
When rear automobile with this automobile speed of a motor vehicle set in relative to sensing speed of a motor vehicle control circuit unit, when rear car approaches the distance of this automobile, namely the relative distance between two cars is less than comprehensive segmentation warning sensing circuit A rice warning sensing circuit, B rice warning sensing circuit, C rice warning sensing circuit, time in the fence coverage of D rice warning sensing circuit and each warning sensing circuit: sensing circuit performs mouth will export executive signal to crashproof execution OR circuit input end, crashproof executive command passes to control output circuit through crashproof execution OR circuit, control the crashproof mouth of output circuit to be connected with centralized control unit input end, be transported to actuating system power pack section through control center's unit execution mouth and stretch out the instruction of signal input part execution Anti-bumping protection.
When actuating system power pack section is after namely the Anti-bumping protection instruction receiving control system output stretches out signal; power pack section motor stretches out positive dirction and rotates; buffer arm part is protruding by buffer arm under the effect of left pars contractilis, right pars contractilis, is formed and carries out Anti-bumping protection.
When rear automobile with this automobile speed of a motor vehicle set in relative to sensing speed of a motor vehicle control circuit unit; when rear car approaches the distance of this automobile; namely when the relative distance between two cars is less than in the fence coverage of comprehensive segmentation warning sensing circuit A rice warning sensing circuit, B rice warning sensing circuit, C rice warning sensing circuit, D rice warning sensing circuit and each warning sensing circuit; buffer arm part is all protruding by buffer arm under the effect of left pars contractilis, right pars contractilis, is formed and carries out Anti-bumping protection.
Represent that each sensor-based system comprehensive segmentation sensing circuit Anti-bumping protection state is normal, segmentation sensing circuit as comprehensive in certain sensor-based system can not be formed and carry out Anti-bumping protection, then represent this sensor-based system comprehensive segmentation sensing circuit mal; As such as all do not carried out row Anti-bumping protection, then may be actuating system medium power part, subtract and hit part, orbit part, telescopic section, there is fault in rear anti-crash thick stick part.
3, check sensor-based system comprehensive segmentation sensing circuit automatic clear state successively: though when rear automobile is travelling with this automobile speed of a motor vehicle set in relative to sensing speed of a motor vehicle control circuit unit, but the distance of rear car and this automobile, namely when the relative distance between two cars is greater than in the fence coverage of comprehensive segmentation warning sensing circuit and each warning sensing circuit: control output circuit and eliminate clearing mouth by output clearing restoring signal, recovery unit automatic reset circuit is reset to control center's unit, clearing recovery instruction is issued actuating system power pack section retraction signal input part by resetting recovery output circuit by automatic reset circuit, actuating system telescopic section is sent reset signal, buffer arm automatically retracts to initial position, automatically terminate crashproof state.
When rear automobile with this automobile speed of a motor vehicle set in relative to sensing speed of a motor vehicle control circuit unit, when rear car approaches the distance of this automobile, namely when the relative distance between two cars is less than in the fence coverage of comprehensive segmentation warning sensing circuit A rice warning sensing circuit, B rice warning sensing circuit, C rice warning sensing circuit, D rice warning sensing circuit and each warning sensing circuit, buffer arm is all automatically retracted to initial position by buffer arm part under the effect of left pars contractilis, right pars contractilis, automatically terminates crashproof state.
Represent that each sensor-based system comprehensive segmentation sensing circuit Anti-bumping protection state is normal, buffer arm can not be automatically retracted to initial position by segmentation sensing circuit as comprehensive in certain sensor-based system, automatically terminate crashproof state, then represent this sensor-based system comprehensive segmentation sensing circuit mal; As all buffer arm automatically not retracted to initial position, automatically terminating crashproof state, then may be actuating system medium power part, subtract and hit part, orbit part, telescopic section, there is fault in rear anti-crash thick stick part.
Nine, carry out manually removing crashproof status checking:
When crashproof state manually removed by needs, only need press and reset recovery unit clearing recovery button, clear command will be passed to control center's unit, clear command is passed to actuating system power pack section again by control center's unit, when actuating system power pack section performs after the reset signal receiving control system output, the buffer arm adapter shaft of buffer arm part, buffer arm, at left pars contractilis, will be retracted in car body under the effect of right pars contractilis.
It is normal that expression carries out manually removing crashproof state; If the buffer arm adapter shaft of buffer arm part, buffer arm are at left pars contractilis, will not be retracted in car body under the effect of right pars contractilis, then represent manual clear circuit, automatic reset circuit breaks down.
Ten, drop into circuit unit manual-lock circuit to check:
When steering vehicle carries out special traveling, when not needing defencive function, available manual-lock fender guard, the vehicle traveling of closing this fender guard is the same with not installing this fender guard represents normal; Then represent as do not closed and drop into circuit unit, manual-lock circuit breaks down.
