Detailed description of the invention
Below in conjunction with accompanying drawing, following further illustrating is done to the utility model:
As shown in Figure 1, the utility model comprises: signal output apparatus 1, signal pickup assembly 2, information circuits device 3, actr 4 and controlled device 5, signal output apparatus 1 comprises drg 6, sensor 1 and sensor 28, signal pickup assembly 2 is by entire car controller 9 collection signal, information circuits device 3 is by gateway 10 and be connected to the power CAN 11 at gateway 10 two ends and comfortable CAN 12 is formed, actr 4 is by car body controller 13 Received signal strength and perform an action, controlled device 5 comprises one-level stoplight stop lamp 14 and multistage stoplight stop lamp 15, the on-off signal mouth of drg 6 connects one-level stoplight stop lamp 14 by sensor 1, the analog signal output of drg 6 connects entire car controller 9 by sensor 28, the mouth of entire car controller 9 connects power CAN 11, power CAN 11, gateway 10, comfortable CAN 12 is set up information and is transmitted loop, the mouth of comfortable CAN 12 connects car body controller 13, the mouth of car body controller 13 connects multistage stoplight stop lamp 15, drg 6, sensor 1, one-level stoplight stop lamp 14 forms common tail-light control system, i.e. one-level brake light control system, sensor 28, entire car controller 9, power CAN 11, gateway 10, comfortable CAN 12, car body controller 13, multistage stoplight stop lamp 15 form multistage taillight control system, the i.e. taillight control system of the strong and weak level of prompting brake, two systems are separate is independent of each other for this, and namely the fault of multistage taillight control system can not have influence on original brake system, the taillight lamp group of this multistage stoplight stop lamp 15 is provided with at least two or more, or the taillight lamp group of multistage stoplight stop lamp 15 is gradient color car light, wherein, information is transmitted loop and is gathered analog signal by entire car controller 9 and be packaged into CAN message signal, gather CAN message signal by gateway 10 by power CAN 11, and after carrying out unpacking and re-grouping package, be passed to car body controller 13 by comfortable CAN 12.
The utility model is correlated with for the multistage Warning light active safety of self-propelled vehicle and unpowered vehicle brake system and control system control, the analog signal that present situation condition brake pedal exports can connect entire car controller VCU, brake pedal has a digital output modul and directly controls stoplight stop lamp simultaneously, stoplight stop lamp signal is made to ensure very high real-time and stability, and the utility model carries out improving and optimizing on original brake system, the multistage stoplight stop lamp of classification is adopted to strengthen active safety function.
The demand braking force message that the utility model is sent in power CAN by gateway collection entire car controller VCU, restructuring is unpacked to message, digital quantity conversion is carried out to analog signals, then the position signal being converted to respective numbers according to taillight switch amount demand reassembles into CAN message, send to the car body controller BCM in comfortable CAN, the position signal that car body controller can be sent according to gateway carries out taillight control, thus realizes the control of multistage stoplight stop lamp.Achieve when chaufeur steps on brake pedal, the stoplight stop lamp of former automobile also can carry out highlighted according to original logic, and step on the brake pedal of the different degree of depth according to chaufeur, car body controller BCM can control taillight and carry out multistage highlighted simultaneously.
The utility model adds gateway apparatus and establishes information circuits on the basis of former automotive control system, braking information rear car chaufeur better being passed on to front truck is achieved at lower cost by information forwarding unit, improve the active safety of vehicle drive, reduce rear-end collision odds.
Present stage, automobile all can have entire car controller VCU and car body controller BCM usually, but but lack the information circuits device transmitted by speed-slackening signal, increase gateway apparatus and can set up transmission of information loop, and at gateway, fireproof brickwork is set, the safety of further guarantee net control and stability, usual gateway also can integrate with instrument controller, serves the same role and has better integrated level, so the utility model structural system device can well be controlled cost.Revise car body controller BCM logic and lead-out terminal interface, increase the object that multistage stoplight stop lamp can realize multistage brake, whole system Cost optimization is low, and system dependability is high simultaneously.
The implementation method of improved cascade brake active safety system described in the utility model; comprise the following steps: in signal output apparatus; drg usually has two paths of signals and exports; be respectively a path switching signal; stepping on brake pedal when chaufeur will by signal activation, and when on-off signal is activated, the one-level stoplight stop lamp in common tail-light control system can immediately be lit; if at this moment chaufeur just gently touches on the brake, conventional brake lamp is highlighted.Another road is analog signal, can export the analog signals such as 0-5V or 0-2.5V according to the different brake pedal degree of depth.Analog signal the tread in degree of depth different according to brake pedal can change output signal (0-5v or 0-2.5v), entire car controller VCU can gather this road analog signal and then be packaged into CAN message signal, gateway information loop apparatus gathers CAN message signal by power CAN, then carry out unpacking re-grouping package, be delivered to car body controller BCM by comfortable CAN again, information of setting up transmits loop.Transmit loop by information, car body controller BCM can receive signal command, then according to signals different in CAN message, lights the multistage stoplight stop lamp of the varying number in multistage taillight control system, realizes actr and controls controlled device.When chaufeur progressively loosen the brake, same signal can according to the above-mentioned mode of intelligence transmission, multistage stoplight stop lamp is extinguished gradually, until chaufeur discharges brake pedal completely, multistage stoplight stop lamp then extinguishes completely, and one-level stoplight stop lamp extinguishes, complete the process of release brake pedal, whole control flow is the same.
In the utility model, taillight lamp group can carry out the change of different magnitude according to concrete demand, such as: if need braking force to be divided into four grades, remove former car braking car light, also need external 3 lamp sources composition lamp group, again by carrying out classification to the outputting analog signal of brake pedal, respectively to secondary, three grades, level Four taillight carries out light on and off control, brake pedal signal is subdivided into four grades by theory.If need to show brake taillight effect accurately further, can expand taillight lamp group, also taillight lamp group can be changed into the display of gradient color car light.That is, taillight lamp group quantity can change according to demand, if demand is N level, then needs external taillight quantity to be N-1.If or do not use multiple taillight to represent the brake depth, also could change taillight into gradual change aspect.
