Abstract

The invention relates to a vehicle-mounted data recorder, a vehicle-mounted data recording method and a vehicle so as to solve a problem that in the prior art, when a driving assistance system has a fault, the fault cannot be rapidly positioned. The vehicle-mounted data recorder comprises an event triggering module, a data caching module and a data storage module, wherein the event triggering module is used for sending out a triggering signal when detecting out a storage event in which data storage needs to be carried out; the data caching module is used for carrying out circular caching on data provided by a vehicle-mounted gateway in a covering mode; and the data storage module is used for taking a prescribed period before and after the triggering signal is sent as a storage period, reading cached object data in the storage period from the data caching module and carrying out storage when receiving the triggering signal.

Description

technical field [0001] The invention relates to the field of vehicle-mounted data storage, in particular to a vehicle-mounted data recorder, a vehicle-mounted data recording method and an automobile. Background technique [0002] With the development of automotive intelligent driving technology, more and more driver assistance technologies are mass-produced and mounted on passenger cars. The integration of automotive intelligent driving technology is getting higher and higher, and the safety and comfort have been greatly improved. L2 autonomous driving technology integrates vehicle longitudinal and lateral control, and can keep the vehicle cruising in the lane. The driver only needs to pay attention to the conditions ahead of the vehicle and be ready to take over the vehicle at any time. Compared with traditional automotive technology, intelligent driving technology pays more attention to the perception of driving environment in the development stage, and provides correspond...
