Problems solved by technology

[0003] However, when the event data recorder in the prior art collects and stores data from passenger vehicles and commercial vehicles, it mainly collects and collects data in automobile collision events. The collected data is not comprehensive enough, and many important data are omitted.
Especially with the popularity of automobile driving assistance systems and intelligent driving systems, there is a lack of collection and reception of vehicle driving event data such as active and passive safety systems and intelligent driving system data, vehicle chassis system data, power system data, body electronic system data, etc. , which is not conducive to the subsequent analysis of vehicle driving events, driver assistance system data (such as data required at the ADAS level) and determining the cause of the accident
[0004] In addition, the storage capacity of most traditional event data recorders is limited, and to achieve comprehensive data collection and recording, it is easy to exceed the storage capacity of the event data recorder, resulting in the new event data cannot be effectively recorded , or when the previous event data is overwritten, important event data will be deleted, or a new event data recorder needs to be replaced in time, which will increase user time and cost, resulting in poor user experience

Embodiment 1

[0028] see figure 1 , an embodiment of the present invention provides an event data recording method, the method comprising:

[0029] S10. When a passive safety event occurs to the vehicle, it is recorded as the first locking condition; this type of safety event is usually a collision event that occurs (is about to occur) to the vehicle.

[0030] S20. When an active safety event occurs to the vehicle, record it as a second locking condition; wherein the priority of the first locking condition is higher than the priority of the second locking condition.

[0031] Further, the active safety events include: vehicle active safety events and driving assistance events.

[0032] Further, when the vehicle active safety event occurs, it is recorded as the first sub-locking condition of the second locking condition; when the assisted driving event occurs, it is recorded as the second sub-locking condition, wherein the first A sub-locking condition has a higher priority than the second ...

Embodiment 2

[0100] See figure 2 , Embodiment 2 of the present invention mainly introduces an event data recorder corresponding to the above-mentioned driving event data recording method. This event data recorder mainly comprises: controller (as MCU, microcontroller) 1, memory 2 and power supply unit, described power supply unit provides power for described controller 1 and described memory 2, described event data recorder It also includes: an ADAS data detection unit 62, which detects the collision risk data and / or lane deviation data of the vehicle in the ADAS state, and sends them to the memory 2 for storage.

[0101] In a preferred embodiment, the event data recorder further includes: a vehicle body data detection unit 63 for detecting vehicle body information.

[0102] In a preferred embodiment, the vehicle body data detection unit 63 includes: a first sensor, used to detect whether the torque request variation of the steering wheel of the vehicle exceeds a first preset threshold, w...

Embodiment 3

[0143] See Figure 4 , on the basis of the above-mentioned embodiments 1 and 2, the present invention also proposes an event data recording device corresponding to the driving event data recording method, which mainly includes:

[0144] The first locking condition recording unit 100 is used to record as the first locking condition when a passive safety event occurs in the vehicle;

[0145] The second locking condition recording unit 200 records as a second locking condition when an active safety event occurs to the vehicle; wherein the priority of the first locking condition is higher than that of the second locking condition.

[0146] For a detailed description of the functional units corresponding to the method for recording driving event data in the event data recording device, please refer to Embodiments 1 and 2, which will not be repeated here.

Abstract

The invention relates to a driving event data recording method and device, and an event data recorder. The driving event data recording method comprises the steps of: when a vehicle generates a passive safety event, taking a first locking condition record; and when the vehicle generates an active safety event, taking a second locking condition record, wherein the priority of the first locking condition is higher than the priority of the second locking condition. The vehicle driving event record data is locked according to the features of a vehicle intelligent driving system to prevent the vehicle driving event record data from being covered to cause important event data loss and reduce the demand of the storage space amount of the event data recorder, and the record of the event data is beneficial to the subsequent technical analysis and confirmation of responsibility for traffic accidents.

Description

technical field [0001] The invention relates to the technical field of data recording equipment, in particular to a method and device for recording driving event data and an event data recorder. Background technique [0002] With the development of the automobile industry and the transportation industry, intelligent vehicles and intelligent transportation have become one of the main directions of today's automotive technology development. In order to monitor the various states of the vehicle in real time, the current vehicle driving information recording devices can be roughly divided into two categories, one is the vehicle driving recorder for the purpose of vehicle operation management, which is used to monitor the vehicle speed, time, mileage, location and A digital electronic recording device that records and stores other status information related to vehicle driving and can output data through data communication. The use of this intelligent traffic monitoring tool can ...
