摘要:
The invention relates to a device and method for increasing the safety of a motor vehicle. A first sensor unit (2) detects the environment, in particular free spaces and objects (0) and the position and motion of said objects. A second sensor unit (20) detects the environment state, a third sensor unit (30) detects the vehicle state, and a fourth sensor unit (40) detects the driver specifications. The data are amalgamated. According to the invention, a driving safety coordinator (6) is provided, which calculates the risk of collision on the basis of a risk evaluation, and the driving safety coordinator (6) determines pre-collision phases (P1, P2, P3, P4a, P4b) of the motor vehicle (1) with regard to the object (0).

The invention relates to a method for carrying out an automatic braking action, whereby at least one variable representing the actuation of the brake pedal is determined and an automatic braking action is then triggered if at least one threshold value (brake pedal actuation-threshold value) of the variable representing the actuation of the brake pedal is exceeded, whereby the brake pedal actuation threshold value is altered and/or the variable representing the brake pedal is weighted according at least one driver action, especially a detected movement of the driver's foot before an actuation of the brake pedal of the considered braking action and/or prior to the considered braking action.

The invention relates to a method for regulating the brake pressure in a motorcycle having an anti-lock function and having an integral brake function, wherein by means of the integral brake function, front wheel brake means (9) are actuated in connection with a brake actuation at a rear wheel (HR), and a brake pressure (psollVR) in a front wheel brake circuit (5) is regulated on the basis of a first predefined dependency (f) of a pressure (pmessHZ HR) caused by the brake actuation at the master brake cylinder (8) of a rear wheel brake circuit (6), and wherein in the event of a regulating intervention (32), which takes place on account of the anti-lock function, at the rear wheel (HR), a higher brake pressure (psollVR) is set in the front wheel brake circuit (5) than is set at the present pressure (pmessHZ HR) at the master brake cylinder (8) on the basis of the first dependency (f) when there is no anti-lock regulating intervention, and to a brake system for motorcycles.

The invention relates to a method for determining a roll angle of a motorcycle. Said method is characterized by determining a rolling rate (Formula A) of the vehicle, especially by means of a rotational speed sensor, determining a first roll angle (λ1) from the rolling rate (Formula A), determining at least one additional variable that is characteristic of the driving dynamics, especially a speed (v) and/or a rolling rate (Formula A) and/or an acceleration (Formula C, Formula D) of the vehicle, determining, based on this/these variable(s) that is/are characteristic of the driving dynamics, at least one second roll angle (λ2) and calculating from the roll angles (λ1, λ2), especially by addition (15), the roll angle (λE). The invention also relates to a device for determining the roll angle of a motorcycle.

The invention relates to a brake by-wire actuator for actuating the braking system of a motor vehicle, comprising at least one simulator (2) which can be impinged upon by a brake pedal (1), a signal of the actuation sensor (3) being supplied to an electronic control unit (4) which controls a pressure source according to the signal of the actuation sensor (3), one output of the pressure source being connected to a distributor device (10) for the braking force, and actuates individual wheel brakes (16) of the vehicle. Means are also provided to enable actuation of the brakes by muscular power within a recoil plane. In order to provide an improved recoil plane in a brake-by-wire actuator of the above-mentioned variety, free travel (a) is foreseen between a first actuation component (47), such as a brake pedal (1) or a component (36;21) connected thereto, and an actuation component (37) located downstream in the force flow such that the first actuation component (47) can be mechanically decoupled from force reactions occurring in the vehicle braking system in a by-wire mode.

In order to widen the adjustment range for pressure regulation in a brake system fitted with a brake servo-unit capable of being operated (preferably electromagnetically) independently of the driver's will, the following arrangement is proposed: the hydraulic pressure (PTHz) set in a master cylinder (3) downstream of the brake servo-unit (2) is determined and applied to a pressure regulator (8) following comparison with a pressure setting signal (PSoll); the output value (ISt) of the pressure regulator matches a control current for the electromagnet (7) and is applied to a limiter (12) which sets the boundary values of the desired adjustment range and whose initial value (ISoll) is compared with the value of the current (IEM) applied to the electromagnet (7); the result (IRegel) of the comparison is applied to a current regulator (14) which produces the voltage (UEM) destined to be applied to the electromagnet (7).
