Embodiment Construction

[0022] figure 1 A vehicle 2 in the form of a passenger car waiting to be parked in a side parking space 1 is shown in a typical application of the invention. The parking space 1 is located next to the lateral road boundary 3 between two vehicles 4 , 5 that are already parked next to the road boundary 3 . A vehicle 2 to be parked is driving next to the parking space 1 in the forward direction symbolized by the arrow 7 on the track 6, the vehicle having a sensor device, shown here as an example of a sensor 8 arranged at the right front end of the vehicle, advantageously is an ultrasonic sensor with a lobe-shaped sensing area 9 .

[0023] As can be seen, the length L of the parking space corresponds substantially to the travel distance covered by the vehicle 2 , with deviations caused by the lobe shape of the sensing region 9 being taken into account in the calculation of the length L by a computer in a known manner.

[0024] and figure 2 Shown is the parking situation of th...

Abstract

The invention relates to a method for assisting with the parking of a vehicle (2) in a parking space (1) lateral to the vehicle (2), wherein a faulty length L+ of the parking space (1) is detected by a sensor arrangement of the vehicle (2) as the vehicle (2) passes the parking space (1) on a curved movement path (6). Additionally, to determine the actual length L of the parking space (1), a movement path of the vehicle (2) deviating from straight travel of the vehicle (2) while passing the parking space (1) is detected, for example based on the steering angle of the vehicle (2), and from the path a corrective value for the detected length L+ of the parking space (1) is determined. The actual length L of the parking space (1) is thus determined with high accuracy, without requiring additional measured values, such as the orientation of the parked vehicles (4, 5) or the depth of the parking space (1).

Description

Background technique [0001] The invention relates to a method for supporting a parking process of a vehicle in a parking space arranged at the side of a vehicle to be parked, wherein the length of the parking space is detected by a vehicle sensor system while the vehicle is driving alongside the parking space. [0002] This method is generally known as a driver-assisted parking space location function for finding a parking space, another name for this function is parking space location (PSL). This method is known in particular as a function of the parking space measurement (PLV), which supports the vehicle driver in finding a sufficiently large support space for his vehicle, parking space location being a generalization of the parking space measurement. Parking clearance measurement can work together with parking systems for semi-autonomous parking, where the driver has to operate the vehicle's travel and brake pedals, while steering can also be performed automatically. The s...
