A method for operating an assistance system of a motor vehicle, with a first control unit and with a second control unit, wherein a first rotational speed sensor is connected to the first control unit for recording a rotational speed of a first wheel, wherein a second rotational speed sensor is connected to the second control unit for recording a rotational speed of a second wheel, and wherein the first control unit is coupled to the second control unit using signal technology.

Methods and system are provided for generating regenerative braking torque at a front axle and a rear axle of a vehicle. In one example, the regenerative braking torque may be a function of a normal load applied to the front axle and a normal load applied to the rear axle.

The present disclosure relates to a method of inflating a tire and a central tire inflation system. The system has the tire connected to a pressure port for applying an air pressure via a pneumatic line. An ambient air temperature and a target pressure for the tire is received and a tire inflation rate based on the ambient air temperature and the target pressure is calculated. An estimated pressure of the tire based on tire inflation rate is estimated and the tire is inflated at the calculated tire inflation rate. A pressure of the tire is measured and a correction factor based on a ratio between the measured pressure and the estimated pressure is calculated. The tire inflation rate using the correction factor is corrected and the tire is inflated at the corrected tire inflation rate until the target pressure is reached.

[Problem] The present invention obtains a controller and a control method capable of appropriately recording desired information in a recording unit of a straddle-type vehicle.

[Means for Resolution] In the controller and the control method according to the present invention, recording of information by a recording processor is controlled, the recording processor continuously acquires target information as a recording target and can execute event data recording for recording partial information, which is information acquired in a period including a shock application time at which the straddle-type vehicle receives a shock, of the target information as event data. In addition, selection of whether to prohibit or permit the event data recording is made in the case where it is determined that the straddle-type vehicle is brought into an off-ground state where a wheel of the straddle-type vehicle comes off the ground.

The present invention obtains a controller capable of improving safety of a motorcycle.

The controller that controls vehicle body behavior of the motorcycle includes: an acquisition section that acquires trigger information generated in accordance with peripheral environment of the motorcycle; and an execution section that initiates a control mode making the motorcycle execute an automatic brake operation in accordance with the trigger information acquired by the acquisition section and makes the motorcycle generate a braking force. The acquisition section further acquires seat load information that is information of a load received by a seat of the motorcycle, and the execution section changes the automatic brake operation, which is executed in the control mode, in accordance with the seat load information acquired by the acquisition section.

A method for determining a contact force on a utility vehicle includes providing the utility vehicle with a first wheel axle and a second wheel axle, determining a drive slip of the second wheel axle, and a road surface-specific determination data set associated with a traction coefficient in dependence on the drive slip, and determining the contact force on the second wheel axle based on the drive slip of the second wheel axle and the road surface-specific determination data set.

The safety device comprises a vehicle body inclination angle detector to detect an inclination angle of the vehicle body. In a vehicle body attitude in which the inclination angle of the vehicle body detected by the vehicle body inclination angle detector is less than a predetermined inclination angle, while any travel operation by the travel operation device is not performed, when a steering operation by the steering operation device is performed, the travel controller performs control to release braking the front wheels and the rear wheels by the brake device and to make the steering device turn the front wheels and the rear wheels in accordance with the steering operation.

The invention relates to an operating method for an automatic transmission, particularly for an automatic variable-speed transmission and/or dual-clutch transmission, for a motor vehicle. The automatic transmission can be operated in a cost-effective manner, particularly with reduced component wear and increased service life, and/or the driving comfort of the vehicle can be improved such that when lifting of at least one driven vehicle wheel off the roadway during braking is detected by the operating method, then for the length of said braking process, in the event of an incomplete gear change into a gear of the transmission, the engagement of a gear is prevented and/or the beginning of a gear change into a gear of the transmission is prevented.

A method for preventing a forward flip-over or a flip-over about the vehicle transverse axis of a single-track motor vehicle, during a braking action of its front wheel. In the method, a lift-off indicator parameter is ascertained, which represents the flip-over hazard by a rear wheel at risk of lifting off or already having lifted off the ground surface, and the braking force at the front wheel is reduced as a function thereof to prevent a flip-over.

The present invention relates to a brake control device and a brake control method for a vehicle comprising a plurality of brakes which are respectively installed on wheels, the brake control device comprising an auto leveling sensor which senses a load state of the vehicle according to a change in an angle; a control unit which calculates a correction value according to the load state of the vehicle sensed by the auto leveling sensor; and an electronic brake booster which corrects a predetermined braking power set according to a brake pedal force with the calculated correction value so that the braking operation of each brake is made.
