Definitions

• the invention relates to a display device for a speed controller with
• Distance control function and stop & go function with at least one first display element for displaying the operating status of the speed controller and a second display element for indicating that a target object for the distance control is detected.
• adaptive speed controllers are known, which are also known as ACC
• Adaptive Cruise Control Not only do these systems make it possible to control the speed of one's own vehicle to a desired speed selected by the driver, but they also allow automatic control of the distance to a vehicle in front.
• the distance and the relative speed of the vehicle in front are measured, for example, by means of a radar sensor, and by intervention in the drive and / or braking system of the vehicle, the speed is controlled so that the preceding vehicle is tracked at an appropriate distance.
• the system switches to a state in which an automatic restart is only possible after driver confirmation.
• This driver confirmation may be, for example, that the driver briefly taps the accelerator pedal, pressed a button or the like.
• the reason for this restriction is that, after a long downtime, it can no longer be expected that the driver will monitor the traffic environment with the necessary attention. If, for example, during a traffic jam, the standstill lasts longer, for example, longer than 20 minutes, the automatic restart function is completely disabled because the driver is likely after such a long time is no longer aware that the Stop & Go system is still active.
• a display device for a cruise control in which a plurality of optical display elements are provided on the dashboard. Preferably, these display elements are integrated in the speedometer of the vehicle.
• a first display element is formed by a series of light emitting diodes arranged along the speed scale of the tachometer. If the ACC system is active and a desired speed is set, this will be indicated by a light emitting diode on the speed scale indicating the desired speed selected.
• two signal lamps are provided, which indicate whether the ACC function or the Stop & Go
• Function is active, activatable or inactive.
• the transition between the states “active” and “activatable” is indicated, for example, by a color change of the relevant signal lamp. If the stop & go function is only active or activatable when a target object is detected, the corresponding signal lamp implicitly also provides information as to whether a target object has been detected.
• display devices for conventional ACC systems without stop & go function usually have at least two display elements, a first of which indicates the operating status, while the second indicates whether a target object is detected.
• the display device according to the invention is designed to different standstill states of the speed controller by different

• the second display element for indicating that a target object is detected is preferably formed by a further signal lamp.
• the transition to the standstill state in which an automatic restart is possible only after driver confirmation, can be identified by the fact that the first display element goes out while the indicator light, which indicates the target object, still lights up.
• the driver is also made aware of the change of state by an acoustic signal, such as a gong.
• At least one of the first and second display elements may assume at least two active states in addition to the disconnected state, for example by a color change or flashing of the relevant signal lamp.
• the various standstill states can then be represented in a more differentiated manner.
• this indication is amplified by an acoustic signal.
• the standstill state in which an automatic restart is not possible and the driver is asked to take over the control itself, by a color change at least the first display element symbolize.
• This takeover request is also preferably reinforced by a characteristic warning tone.

• FIG. 1 a known speed controller with ACC function and Stop & Go function is shown as a block diagram.
• a radar sensor 10 provides tracking signals to a control unit 12, which evaluates the locating signals according to known algorithms and engages in the not shown drive and / or braking system of the vehicle to control the speed of the vehicle either to a desired speed selected by the driver or, if Radarsensor a preceding vehicle was located on its own lane to adapt the speed to that of the preceding vehicle, the target object.
• the ACC function can be activated.
• a special key 16 is provided in the example shown.
• the Stop & Go function can also be activated automatically together with the ACC function.
• the driver can set the current speed as the desired speed.
• a key 20 serves to gradually decrease the desired speed.
• the ACC function and the stop & go function can be deactivated.
• the control unit 12 further receives signals from a brake pedal sensor 24 and a
• Accelerator Pedal Sensor 26 Actuation of the brake pedal, similar to the actuation of the key 22, causes the system to be deactivated. With the help of the accelerator pedal sensor 26, the driver can enter a start-up confirmation by pressing the accelerator pedal, as will be explained in more detail later.

• an acoustic signal transmitter 32 and a display controller 34 which is shown for clarity as a separate block, in practice, however, may also be integrated into the control unit 12.

• the system is in a state 36 in which, depending on the situation, a regulation to the desired speed or, if a target object is present, a distance control takes place.
• a transition to a state 40 takes place according to arrow 38, and the own vehicle is automatically braked until it comes to rest at an appropriate distance behind the preceding vehicle.

• This driver confirmation may consist, for example, in a brief tap of the accelerator pedal.

• FIG. 4 shows the corresponding display image in the event that the system is in state 36 and there is a free-running situation, ie that the radar sensor does not locate a target for the distance control. Accordingly, the indicator lamp 58 is extinguished here, and the actual speed coincides with the desired speed indicated by the LED 56a.

By the illumination of the two indicator lights 54 and 58, the driver is informed that automatic starting is possible in this standstill state, ie that the front vehicle is automatically tracked as in the situation shown in FIG.

• the display image changes in the manner shown in FIG.
• the two signal lamps 54, 58 light up, but in a different color, for example in red. This informs the driver that he should deactivate the cruise control and take control himself. If the driver then presses the button 22 ( Figure 1), the system is deactivated and the indicator lamps 54, 58 go out.
