Embodiment Construction

[0040] figure 1 A schematic representation of a driver-controlled vehicle, such as a passenger car 1 , including features of the vehicle relevant to the invention is shown. The location of these features within the vehicle is not affected by figure 1 Schematic representation of limitations in .

[0041] The vehicle 1 comprises: wheels 10; a steering wheel assembly 20 with a steering wheel angle sensor 22; a gearbox 40 with means 42 for determining the currently selected gear; a control device 100 with a memory 110 for storing data; and Driver interface 50 . Proximity sensors 40 are provided on both sides of the vehicle. The driver interface 50 includes an instrument panel 52 having a visual display 54 , a buzzer or other audible device 56 and a collision warning selection button 58 .

[0042] A steering wheel angle sensor 22 is provided on or adjacent to the steering wheel assembly 20 . The sensor 22 senses the position of the components of the steering wheel assembly and...

Abstract

A method and apparatus for providing a collision warning for a driver-controlled vehicle comprising:a) storing data relating to the geometry of a side of the vehicle; b) receiving data from at least one sensor for detecting an obstacle in the proximity of the vehicle; c) storing a position of the detected obstacle relative to the vehicle; d) measuring or inferring the instantaneous steering angle; e) predicting the trajectory of the side of the vehicle based on the geometry of the side of the vehicle and the instantaneous steering angle; f) determining whether the vehicle will collide with the detected obstacle based on the predicted trajectory and the stored position of the detected obstacle; g) calculating a position of a predicted collision zone on at least one of: the side of the vehicle and on the detected obstacle; h) providing a visual indication to a driver of the vehicle of the trajectory of the vehicle relative to the detected obstacle; and i) if the predicted trajectory of the side of the vehicle will result in a collision, providing a visual indication of the position of the predicted collision zone on at least one of: the side of the vehicle and position of the predicted collision zone on the detected obstacle.

Description

technical field [0001] The invention relates to a method of providing collision warning for a driver-controlled vehicle. The invention also relates to a collision warning device in a driver controlled vehicle. Background technique [0002] Park assist is known to warn the driver of a vehicle of objects that are too close to the front and / or rear of the vehicle. In such systems, proximity sensors are typically installed in the front and / or rear bumpers. An audible warning (usually a beep) is heard when an object is detected close to the front or rear of the vehicle. As the vehicle gets closer to the detected object, the frequency of the beeps increases until the object is within a predefined distance from the vehicle, at which point a continuous alarm is heard. [0003] There are several problems with these known parking assistance systems. As the vehicle approaches a detected object, a continuous audible warning is heard without the driver being sure whether an actual co...
