Definitions
- the invention relates to a device and a method for adjusting an actuating device.
- a foot actuation device for a motor vehicle which is adjustable in its relative position to a vehicle seat, is known for example from EP 918 273 AI.
- This comprises a pedal bracket to be fixed to the vehicle, to which a handlebar provided for the purpose of adjustment is articulated with an electromotive adjusting device.
- a number of pedal levers for example for brake and clutch actuation, are in turn pivotably articulated on the handlebar as the actual actuating members 2 and transmit the actuating movement to assigned transmission means such as hydraulic master cylinders, Bowden cables, handlebars or the like.
- transmission means are also conceivable, as is already known, for example, with regard to the accelerator pedals.
- the electromotive adjusting device comprises an electric motor transmission arrangement connected to the on-board electrical system, which can be actuated with electrical switching means.
- the adjustment of steering wheels while driving is associated with an increased risk of accidents if, for example, the adjustment position has not been locked. It is not without reason that the vehicle manufacturer's operating instructions explicitly warn against adjusting the steering wheel while driving.
- the object of the present invention is to provide a device and a method for the electromotive adjustment of an actuating device, which allows greater safety in handling the electromotive adjustment function.
- the actuating device is assigned an electromotive adjusting device for at least one actuating member and an electrically connected control unit, which (control unit) is in turn connected to electrical switching means and that at least one electrically connected to the control unit
- Actuating detection means is provided for monitoring an actuation of the actuating member, so that in the event of a safety-critical state, the tromotor adjustment blocking electrical signal can be output to the control unit, or the current supply to the electromotive adjustment device can be interrupted.
- the object is achieved in that the actuating device is associated with an electromotive adjusting device for at least one actuating member and an electrical control unit connected thereto, which (control unit) is in turn connected to electrical switching means and that wheel speed sensors are provided, which are at least indirectly associated with are connected to the electrical control unit for the adjusting device, so that wheel speed signals arriving in the control unit generate control signals which block the electromotive adjustment, or interrupt energization of the electromotive adjusting device.
- Claim 2 therefore has the object of a solution which uses a vehicle movement as the decisive criterion for an interruption or inhibition of the adjustment process.
- the electrical control unit is also connected via a bus system to a central controller which as the local electrical control units of the comfort area (central locking, mirror adjustment, seat adjustment, electric windows) monitored.
- a central controller which as the local electrical control units of the comfort area (central locking, mirror adjustment, seat adjustment, electric windows) monitored.
- a brake pedal lever with actuation detection means (brake light switch) and an accelerator pedal lever with actuation detection means (electric pedal position transmitter, displacement sensor, actuation switch) are provided as actuation members and connected to the electrical control unit.
- An actuation signal from only one of the actuation detection means causes the adjustment device to be blocked within the control unit. Consequently, claim 2 has another object of the problem which makes a vehicle movement the decision criterion for an adjustment process.
- a clutch pedal lever can additionally be provided with an associated actuation detection means (cruise control switch) and electrically connected to the control unit, so that the described electrically effective blocking of the adjustment function also occurs in the event of a clutch actuation.
- actuation detection means cruise control switch
- the figure also shows a foot actuation device 1 which is adjustable in its position relative to a vehicle seat (not shown) by means of a motor M and which, as actuation members 2, comprises a total of three pedal levers 3, 4, 5, which are attached to a handlebar 6 with the aid of the electromotive adjustment device and each associated drive shaft 7 and gear 8 are adjustable in their relative position to a vehicle seat and pivotally articulated.
- the adjustment of all the pedal levers 3, 4, 5 takes place synchronously, which is achieved according to the exemplary embodiment in that only the gear of the clutch pedal lever 3 is supplied directly by the motor M, while the gear of the other pedal levers 4, 5 each have a pedal lever closer to the engine Tap the drive shaft.
- the handlebar 6 is articulated on an unillustrated pedal bracket, which to a certain extent forms a fulcrum for the adjustment of the foot actuation device 1.
- the electromotive adjustment device is connected via electrical signal lines 9, 10 to an electrical control unit 11, which in turn is connected via signal lines 12, 13, 14 to electrical actuating means 15, 16 (switches) for the adjustment device and independently thereof via a data bus 17 (preferably using the CAN protocol) is connected to a controller 18.
- Each of the switching means 15, 16 is responsible for a specific adjustment direction.
- the controller 18 also be used for other comfort-oriented electromotive vehicle functions, such as, for example, seat adjustment, mirror adjustment, window lifters, central locking or Similar is responsible, and their function is also monitored in terms of on-board diagnosis and for communication between the individual units.
- Such communication is particularly useful in the event of defects in the on-board electrical system, for example when the voltage supply is limited by an on-board battery and a function priority must be implemented among the units. For example, this can result in the fact that only a door closing module (as an emergency operation) is actuated in the event of a power shortage in the sense of a power saving function, or that the electromotive adjustment is blocked because it is an unnecessary comfort unit.
- each actuating member 2 (pedal lever) is assigned an actuation detection means 19, 20, 21, namely an electrical switching or sensor means for monitoring the actuation of the pedal lever, which in turn are connected to the control unit 11 via electrical lines 22, 23.
- the vehicle driver expresses the wish to adjust the foot actuation device by actuating a switching means 15, 16, the signal of which is fed to the control unit 11.
- the control unit 11 queries whether there is a safety-relevant state, that is to say whether the vehicle is moving, for example, or whether there is currently an actuation situation. In the event that no safety-relevant situation has been reported, the control unit 11 transmits corresponding adjustment signals to the electromotive adjustment device. Lie in the control unit 11- However, before actuation signals or wheel speed signals (which characterize a safety-relevant status), the control unit 11 emits a signal that blocks the adjustment or simply interrupts the electrical current supply.
- Whether a blocking signal is emitted or the electrical current supply is interrupted essentially depends on the operating mode of the motor M, because this can be supplied in a conventional manner with direct current, or with the aid of a pulse width modulated signal (PWM), which would require a lock signal from the control unit 11.
- PWM pulse width modulated signal
- the invention can be implemented particularly inexpensively if absolutely necessary components fulfill the function of the actuation detection means 15, 16, so that synergy effects occur.
- This is feasible, for example, with the aid of a brake light switch, which emits a signal anyway as part of a brake application. Consequently, the brake light switch can also be used as actuation detection means 15, 16.
- the clutch pedal lever 3 for a cruise control switch or with regard to an electrified accelerator pedal lever 5 for a pedal position sensor (E-gas potentiometer), which generates a signal for each actuation case.
- the accelerator pedal is also assigned a displacement sensor s, which has an electrical connection 24, 25 to the control unit 11, and a relative adjustment between the accelerator pedal lever 5 and the Brake pedal lever 4 sensed such that the adjustment process is interrupted in the event of an isolated adjustment of the brake pedal lever 4 due to a defect.
- This measure is important for the synchronized distribution of all pedal levers 3, 4, 5, because it prevents the brake pedal lever 4 (and possibly the clutch pedal lever 3) from coming to rest behind the accelerator pedal lever 5 from the driver's point of view.
- the relative position of the individual pedal levers 3, 4, 5 with respect to one another should be maintained with every adjustment and also with a defect in the shaft in question, it having to be taken into account that the actuating element (pad) of the brake pedal lever 4 is usually from the point of view of the vehicle driver is arranged a few millimeters in front of the pad of the accelerator pedal lever 5.
- an electrical control unit 11 is supplied with a switching signal for switching on the electromotive adjustment device.
- the control unit 11 can be supplied with at least one signal from at least one actuation detection means 19, 20, 21. If the actuation detection means 19, 20, 21 do not emit any signal, the adjusting device is operated as intended. However, if an actuation signal is present in the control unit 11, it emits a signal interrupting the adjustment in the direction of the adjustment device or simply interrupts the electrical current supply to the adjustment device.
- the control unit 11 thus identifies a safety-relevant process (actuation, vehicle movement or other states) and interrupts the adjustment process in this case or does not permit it.
- the process can also be carried out by Activity detection means are replaced by a wheel speed sensor, so that a vehicle movement is used as a criterion for the lock described.
- Activity detection means are replaced by a wheel speed sensor, so that a vehicle movement is used as a criterion for the lock described.
- actuation detection means 19, 20, 21 and wheel speed sensors are also conceivable in order to use both vehicle movement and actuation as criteria for canceling or blocking an adjustment.
