Embodiment 1

[0034] The vehicle parking platform is applicable to vehicle wheelbase range: 2400mm-3200mm; wheelbase range: 1400mm-1700mm; rim range: 14-21 inches; maximum axle load: 1200kg; vehicle curb weight: 3000kg(max); front suspension size : 450mm-1000mm; rear suspension size: 500mm-1300mm. The positioning accuracy of the X / Y axis of the parking platform is ±3mm, the inclination is ±1°, and the vehicle yaw angle accuracy error is ±0.1°.

[0035] The target system can move along the Y axis and Z axis. The Y axis movement adopts the form of synchronous belt plus servo motor reducer, and the Z axis movement adopts the movement form of ball screw plus servo motor reducer.

[0036] The programmable logic controller system is Siemens S7-1500 series, which precisely controls the movement of the target system by controlling the servo driver of the same brand as the servo motor.

[0037] The communication diagnostic instrument and the programmable logic control system communicate based on th...

Abstract

The invention discloses a calibration system and a calibration method for an L2-level driving assistance system, belongs to the technical field of advanced driver assistance functions, can be compatible with initialization calibration of various L2-level driving assistance system sensors, and can realize pipelined batch calibration. The calibration system is adopted to send an instruction to control the programmable logic controller system and establish communication with the vehicle controller, an operator does not need to manually operate the target system, and the operation time is shortened; the platform can be compatible with calibration of various vehicle types, the calibration position in the movement stroke range of the target system can be flexibly adjusted on the premise that thecommunication content of the diagnostic apparatus and the controller is not changed, and large-batch production is met.

Description

technical field [0001] The invention belongs to the technical field of advanced driver assistance functions, and in particular relates to a calibration system and a calibration method for an L2 driver assistance system. Background technique [0002] Advanced Driver Assistant System (ADAS), referred to as ADAS, is to use various sensors installed on the car to collect environmental data inside and outside the car at the first time, and to identify, detect and control static and dynamic objects. Tracking and other technical processing, so that the driver can detect possible dangers in the fastest time, so as to attract attention and improve safety. Active safety technology. The sensors used in ADAS mainly include cameras, radars, lasers and ultrasonics, etc., which can detect light, heat, pressure or other variables used to monitor the state of the car. They are usually located in the front and rear bumpers, side mirrors, inside the steering column or windshield of the vehicle...
