Thus, the EDR data unit 131 may read EDR raw data from an accident vehicle according to a corresponding communication protocol. The EDR data unit 131 in the present invention reads EDR raw data, analyzes and translates the EDR raw data to obtain readable EDR data.
Generally, EDR raw data is a hexadecimal data sequence including data elements of vehicle speed, longitudinal speed variation, steering wheel steering angle, accelerator pedal position, brake pedal position state, anti-lock system state, seat belt state, and turn light state.

The EDR data unit 131 may determine a byte position and a hexadecimal value of each data element in the original data sequence according to a standard, and convert the hexadecimal value into an actual physical value capable of reflecting an accident index through a conversion formula.
For example, when the data element is the vehicle speed, the corresponding parsing and translation process is: the 'vehicle speed' data element pair in the EDR data sequenceHexadecimal array Hex = (a) at byte position n-m 1 ,a 2 ,a 3 ,...,a m-n+1 ) Converting the data into a decimal array Dec, and converting the decimal array Dec into a vehicle speed array V = (r) containing m-n +1 data through a formula of' V = Dec 1 ,r 2 ,r 3 ,...,r m-n+1 ) And each data corresponds to a time point of which the time is divided by m-n from preset time-Ts to 0 s. For example, when the byte position corresponding to the "vehicle speed" data element in the EDR data is 30 to 40 and the preset time is-5 s to 0s, the vehicle speed data v i Corresponding to time t i ＝-5+0.5×i(i＝0,1,2,3,4,5,6,7,8,9,10)。

When the data element is a steering wheel steering angle, the corresponding resolving and translating processes are as follows: a hexadecimal array Hex = (a) corresponding to a data element of a steering wheel corner in an EDR data sequence on byte positions n-m 1 ,a 2 ,a 3 ,...,a m-n+1 ) Converting the decimal array Dec into a decimal array Dec, and converting the decimal array Dec into a Steering wheel Steering Angle array Steering-Angle = (r) containing m-n +1 data through a formula of Steering-Angle = Dec × 5-780 1 ,r 2 ,r 3 ,...,r m-n+1 ) And each data corresponds to a time point of which the time is divided by m-n from preset time-Ts to 0 s.
When the data element is the position of the accelerator pedal, the corresponding analysis and translation processes are as follows: corresponding the data element of the 'accelerator pedal position' in the EDR data sequence to a hexadecimal array Hex = (a) on byte positions n-m 1 ,a 2 ,a 3 ,...,a m-n+1 ) Conversion to decimal numberThe set Dec is then converted to an accelerator pedal position array Acc-pedal = (r) comprising m-n +1 data by the formula "Acc-pedal = Dec = 1 ,r 2 ,r 3 ,...,r m-n+1 ) And each data corresponds to a time point divided by m-n from preset time-Ts to 0 s.
When the data element is the position state of the brake pedal, the corresponding analysis and translation processes are as follows: a hexadecimal array Hex = (a) corresponds a data element of the brake pedal position state in the EDR data sequence to a byte position n-m 1 ,a 2 ,a 3 ,...,a m-n+1 ) Converting into a decimal array Dec, and closing through a formula of 0; 1: on ", into a brake pedal position state array Brk-pedal = (r) containing m-n +1 data 1 ,r 2 ,r 3 ,...,r m-n+1 ) And each data corresponds to a time point of which the time is divided by m-n from preset time-Ts to 0 s.
When the data element is in an anti-lock system state, the corresponding analysis and translation processes are as follows: a hexadecimal array Hex = (a) corresponding to the data element of the anti-lock system state in the EDR data sequence on byte positions n-m 1 ,a 2 ,a 3 ,...,a m-n+1 ) Converting into a decimal array Dec, and then through a formula of' 0: not activating; 1, activating; 2: fault ", converted into ABS = (r) ABS status array containing m-n +1 data 1 ,r 2 ,r 3 ,...,r m-n+1 ) And each data corresponds to a time point divided by m-n from preset time-Ts to 0 s.

The data translation sub-unit 1312 translates a data element and sends the corresponding accident index data to the accident report generation module 15. Correspondingly, the accident report generating module 15 includes a template retrieving unit 151 and a report filling-in unit 152. The template retrieving unit 151 retrieves a report template including one or more of a preset pattern, parameter fields of a plurality of accident indicators, a data description field, a watermark, a vehicle information field, a witness field, a signature field, and the like, the preset pattern, for example, a layout of each component of the report, such as a subject name, a body, a watermark, a signature/signature, and the like. The text may include vehicle information fields, parameter fields for the index data, data description fields, and the like. The signature/signature includes a prover field and a signatory field. The preset style refers to a layout, a font size, a font style, a color, and the like. The subject name and the watermark can be preset in the template.
The report filling unit 152 fills the accident vehicle information input by the data input module 12 into the vehicle information field, fills the evidence taker information input by the data input module 12 into the evidence taker field, and writes the accident index data corresponding to the translated EDR data element into the corresponding parameter field in the report template, as needed, so that an accident report can be obtained.
In addition, the EDR controller in the vehicle reads the event occurrence time (T) 0 ) The EDR controller is used for acquiring the machine time from other electric control systems such as a vehicle-mounted host system, a vehicle-mounted positioning system and the like, and the event occurrence time (T) read by the EDR controller is caused by machine errors, faults and the like 0 ) There is likely to be a deviation from the actual time. In order to eliminate the time deviation, the EDR data unit 131 further includes a time correction subunit 1313, as shown in fig. 5, which is connected to the first data reading subunit 1311, and when the specific source system of the event occurrence time in the accident vehicle EDR controller is determined, and the system machine time data can be read in real time, and it can be confirmed that the system machine time data is not subjected to the problem faults such as re-timing and stopping timing after the accident, and the like, the system machine time T during data reading is determined d And the current actual time T d ' obtains a time error Δ T of the accident vehicle, corrects the time of the read EDR data based on the time error Δ T, and then transmits the time-corrected data to the data translation sub-unit 1312.
For example, the time error Δ T is obtained by the following equation:
ΔT＝T′ d -T d formula 1-1
Wherein, T d To system machine time, T d ' is the current actual time.
Actual event occurrence time T 'after error elimination' 0 The method comprises the following steps:
T′ 0 ＝T 0 -ΔT＝T 0 -(T′ d -T d )
through the time correction processing, the time accuracy of the EDR original data can be ensured.
