Compared with the prior art, the invention has the beneficial effects that: the BDM domain controller-based fuel cell hydrogen energy automobile electrical architecture platform is modularized and integrated, and is based on a car body domain controller, an automatic driving domain controller and an intelligent cabin domain controller, so that a perfect electrical architecture platform is realized.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, the present invention provides a technical solution: the BDM domain controller-based fuel cell hydrogen energy automobile electrical architecture platform comprises an automatic driving domain controller, a vehicle body domain controller and an intelligent cabin domain controller, wherein the automatic driving domain controller, the vehicle body domain controller and the intelligent cabin domain controller are connected through a Chais CANFD, and the Chais CANFD is connected with ESP, iBooster, EPS, ACU; the automatic driving domain controller, the Vehicle body domain controller and the intelligent cabin domain controller are also connected with each other through a Vehicle CANFD, and the Vehicle CANFD is connected with a motor controller, a hydrogen tank controller, a battery management system and a fuel cell control system; the autopilot domain controller is also coupled to the intelligent cockpit domain controller via ETHERNET.
The intelligent cabin domain controller includes T-BOX, IVI, IC.
IVI integrates audio and video functions, smart phones and multimedia device images and applications.
The T-BOX is used for communicating with a background system/a mobile phone APP, realizing vehicle information display and control of the mobile phone APP, and realizing vehicle-mounted components such as an automobile Telematics function, an emergency rescue telephone function and the like.
The body domain controller includes BCM, PEPS, TPMS, EPB, ESCL, AC, CCU, LSPM, DSM, HMC.
The autopilot controller includes an autopilot module, a 360 panorama parking system, an ACC, AEB, a lane keeping module.
360 panorama parking system, through installing the front on the vehicle, back, left and right four cameras integrated vehicle surrounding situation, know that the vehicle is peripheral, the blind area of sight is in the display panorama, also can show the single view of arbitrary party, and position and the distance of cooperation scale line pinpoint barrier, let the car owner can see 360 degrees panorama aerial views in the week directly perceivedly through the display screen, no longer have any blind area of vision, the difficult problems such as parking income position, narrow road meeting, obstacle avoidance from the beginning.
In the ACC, the sensor sends instructions to the executor to determine the running state according to the running states of the front vehicle and the own vehicle after the calculation and judgment of the ECU, and scans the front vehicle, so that the sensor can effectively relieve driving fatigue and improve safety under the conditions that vehicles on the road strictly keep traffic rules and etiquette and do not forcibly change lanes and queue.
The lane keeping module is used for keeping the vehicle on the lane through the identification line of the camera-mounted identification driving lane, if the vehicle approaches the identified identification line and possibly breaks away from the driving lane, the driver is noticed through vibration or sound of the steering wheel, the steering wheel is slightly rotated to correct the driving direction, the vehicle is positioned on the correct lane, and if the steering wheel detects unmanned active intervention for a long time, an alarm is sent out to remind the driver.
The BDM light LIN line is connected with the car window anti-clamping module, the rainfall sunlight sensor and the like. The car window anti-clamping module realizes a car window anti-clamping function through the arrangement of the sensor; the rainfall sunlight sensor can timely sense rainfall and sunlight so as to realize feedback.
The BDM domain controller-based fuel cell hydrogen energy automobile electrical architecture platform is modularized and integrated, and is based on a car body domain controller, an automatic driving domain controller and an intelligent cabin domain controller, so that a perfect electrical architecture platform is realized.
