Embodiment 1
[0043] Embodiment 1 is to apply this method in the real car driving environment.
[0044] A representation method of a safe driving space, which includes the following steps:
[0045] S1: After the car is started and running, a compact enclosing volume of the car is established in advance according to the shape of the car, which is used to detect the spatial distance from the surrounding static and dynamic objects;
[0046]S2: When the running speed of the vehicle exceeds 1km / h, the minimum distance between the surrounding static and dynamic objects and the compact surrounding body of the vehicle is detected in real time; ultrasonic and other methods can be used for distance measurement;
[0047] S3: According to the spatial distance obtained from the detection, the running speed and direction of the vehicle, the acceleration and direction angle of the vehicle, predict the possible collision time interval between the vehicle and the surrounding obstacles when the vehicle is ru...
Embodiment 2
[0051] Embodiment 2 is to apply this method in the environment of a car driving simulator.
[0052] A representation method of a safe driving space, which includes the following steps:
[0053] S1: After the car is started and running, a compact enclosing volume of the car is established in advance according to the shape of the car, which is used to detect the spatial distance from the surrounding static and dynamic objects;
[0054] S2: When the running speed of the vehicle exceeds 1km / h, the minimum distance between the surrounding static and dynamic objects and the compact surrounding body of the vehicle is detected in real time; the spatial distance calculation is performed using the spatial information of various objects in the scene model;
[0055] S3: According to the spatial distance obtained from the detection, the running speed and direction of the vehicle, the acceleration and direction angle of the vehicle, predict the possible collision time interval between the v...

Abstract
The invention discloses a safe driving space representation method. The method comprises the following steps of: S1: previously establishing a compact surrounded body of a vehicle according to the vehicle shape; S2: after the vehicle has a certain speed, periodically detecting a spatial distance between the compact surrounded body and a peripheral object; S3: predicting a time interval of possible collision between the vehicle and a peripheral barrier when the vehicle runs at current speed and accelerated speed in a current driving direction, and obtaining a current minimum collision time interval; S4: according to the current minimum collision time interval, calculating a safe driving space parameter of the vehicle and constructing a safe driving space representation body; and S5: displaying the safe driving space representation body of the vehicle. According to the safe driving space representation method, a safe driving space concept is proposed and a safe driving space determining and representing method is given. According to the detection method, a spatial position related safety state of the vehicle or a vehicle simulator driven by a driver can be evaluated and determined, and a result is expressed in the form of the safe driving space parameter.
Description
technical field [0001] The invention relates to the technical fields of automobile driving, traffic safety, etc., in particular to the fields of automobile auxiliary driving and automobile driving simulation, and in particular to a representation method of a safe driving space. Background technique [0002] In the process of driving a car, the driver needs to make his own judgment on the traffic environment to make the vehicle drive in a relatively safe space. The driver mainly uses it to guide his own driving behavior by observing the position of road traffic facilities in the front window, side window and rearview mirror, the movement status of other traffic participants, and evaluating the interference relationship between his movement route and the vehicle's driving route . [0003] In recent years, automobile manufacturers have designed and produced various assisted driving systems, which use different sensors to obtain the data required for driving, and provide the dr...
