Definitions
- the present invention relates to a method and a device for kinaesthetic warning of the driver of a motor vehicle having an object detection sensor for collision avoidance, wherein in a situation with increased risk of collision, a driver warning is generated by means of the deceleration devices of the vehicle, wherein the deceleration devices are driven in such a way in that the delay gradient is maximized after the time.
- a method and apparatus for haptic display of the distance warning of a motor vehicle which emits a corresponding signal to the driver when falling below a minimum distance to the vehicle in front in conjunction with a distance warning device.
- a haptic signal oscillations of the vehicle or its parts such as steering wheel or driver's seat are proposed.
- the vibrations are caused, for example, by temporary interruption of the ignition of the engine.
- the essence of the present invention is to intuitively inform the driver of a vehicle equipped with an object detection sensor for collision avoidance or collision severity reduction that there is a situation with an increased risk of collision and the driver, for example by braking, intervene in the driving event must to prevent the impending collision. According to the invention this is achieved by the features of the independent claims. Advantageous developments and refinements emerge from the subclaims.
- This reduction of the hydraulic volume, which must be filled with pressure during a deceleration, can be kept small, in particular, by the fact that only the deceleration devices of a vehicle axle, preferably the front vehicle axle, are filled with pressure and shortly thereafter this pressure is released.
- the hydraulic volume of the brake devices can be halved because no longer all deceleration devices, but only the deceleration devices of the front axle must be filled with pressure. This allows you to build a very strong deceleration gradient, which also exerts a rocking motion on the passenger compartment.
- the deceleration gradient is maximized after the time by the braking pressure is built up only in a part of the brake system.
- the part of the brake system in which the brake pressure is built up, the deceleration devices are only one vehicle axle.
- the brake pressure is built up only in the deceleration devices of the front axle.
- the brake pressure is built up only for a short time and then relaxed again.
- a control element which is provided for a control unit of a collision warning device or collision prevention device of a motor vehicle.
- a program is stored on the control, which is suitable for running on a computing device, in particular on a microprocessor and suitable for carrying out the method according to the invention.
- the invention is realized by a program stored on the control program, so that this provided with the program control in the same way is the invention, as the method to whose execution the program is suitable.
- an electrical spoke medium may be used as the control, for example a read-only memory.
- a motor vehicle 1 which has an object detection sensor 2.
- This object detection sensor 2 can be designed, for example, as a radar sensor, as an ultrasound sensor, as a video sensor or as a laser sensor and detects the forward space of the vehicle.
- the object detection sensor 2 is in this case able to detect the distance, the relative speed and the azimuthal angle of any objects present, as well as in conjunction with other input data such as the vehicle's own speed and one's own Delay to determine whether there is a risk of collision with the object ahead and if so, whether this collision can be prevented by an intervention of the driver or by an automatic intervention of a vehicle system for collision avoidance.
- the object detection sensor 2 recognizes that the driver must intervene in the driving event in order to avoid the imminent collision, this causes a kinesthetic warning to the driver by controlling the deceleration devices of the vehicle. Since in this case the purpose of the deceleration is a driver warning and not the most efficient deceleration of the vehicle, it is possible to control only the deceleration devices of one axle, advantageously the deceleration devices of the two front wheels 3, since this does not coincide with the dead volume of the brake devices of the auxiliary wheels 4 Pressure must be filled and in the rest of the brake system, a higher pressure gradient is achievable. In the figure, the front wheels 3 can be seen, as well as the deceleration devices 6 of the front wheels.
- the rear wheels 4 are shown, and the deceleration devices 7 of these rear wheels.
- the brake control device 5 is shown, which receives a signal from the object detection sensor 2, that a kinaesthetic driver warning is to be output and lines shown, which connects the brake control device 5 with the decelers 6 of the front wheels 3 and the deceleration devices 7 of the rear wheels 4.
- These connections can be, for example, hydraulic lines which can be individually pressurized by the brake control device 5 or else these connections can be made electrically, so that the pressure introduction into the deceleration devices takes place directly at the wheels 3, 4, in which case a pressure line to the individual delay means 6, 7 is necessary, which supplies these with the brake pressure, so that directly in the delay means 6, 7, the pressure on the delay means can be introduced.
- the brake control device 5 If the object detection sensor 2 has issued such a warning signal to the brake control device 5, the brake control device 5 generates a deceleration structure on the two front wheels 3 by means of the deceleration devices 6, but not on the rear wheels 4 by means of the deceleration devices 7. This makes it possible, by reducing the filling volume of the brake system as steep as possible pressure rise gradient to reach the deceleration device 6 of the front wheels 3, so that the strongest possible warning effect is achieved kMesthetic signaling. If the brake volume to be filled is halved, in which only the deceleration devices 6 of the front wheels 3 are actuated, the speed is doubled the pressure rise gradient in about.
- the vehicle 1 is a front-wheel drive vehicle in which approximately 70% of the deceleration effect is achieved by the front axle, then only about 70% of the maximum deceleration of the vehicle can be achieved by braking the front axle alone. With regard to the vehicle pressure, this results in a maximized jerk of
