Embodiment Construction
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0017] In one embodiment, as figure 1 As shown, a multi-domain control vehicle-mounted system is provided. The multi-domain control vehicle-mounted system is arranged on a vehicle, and the vehicle includes a plurality of front body equipment located in the front control area of the front end of the vehicle body and a plurality of front body equipment located in the rear control area of the rear end of the vehicle body. Multiple rear body equipment....

The invention discloses a multi-domain control vehicle-mounted system and an automobile. The system comprises a front domain controller installed in a front control area, a rear domain controller installed in a rear control area, and a multimedia control system arranged between the front domain controller and the rear domain controller. Every two of the front domain controller, the rear domain controller and the multimedia control system are in communication connection; the front domain controller monitors a first feedback signal of the front vehicle body equipment in real time and sends the first feedback signal to the multimedia control system when the front domain controller is in a connection success state, and the multimedia control system generates a corresponding first control signal; and the rear domain controller monitors a second feedback signal of the rear vehicle body equipment in real time and sends the second feedback signal to the multimedia control system when the rear domain controller is in a connection success state, and the multimedia control system generates a corresponding second control signal. The system is high in integration degree, system wire harnesses are reduced, and the transmission efficiency of the system is improved by combining a multimedia control system.
Description
technical field [0001] The invention relates to the field of automobile control, in particular to a multi-domain control vehicle system and an automobile. Background technique [0002] With the increase of people's demand for car driving assistance functions and vehicle safety, the electronic and electrical functions on the car are also increasing. In order to realize these increased functions, new controllers, sensors and actuators must be added, thus increasing the wiring harness. length, weight and cost. Especially for pure electric vehicles, the increase in vehicle weight will have a great impact on the mileage. [0003] At present, for various functions on the car, the network architecture of the generally used vehicle controller is divided on the basis of function, that is, a single function is concentrated in one controller for control, for example, power domain, body Domain and other functional divisions. However, the related components that implement different fu...
