A saddle-type vehicle having at least one seat and at least two wheels, at least one electric motor, a motor controller, a rechargeable energy storage system (RESS) such as a battery and battery management system, at least one friction foundation or ABS braking system as a first braking system and at least one electric regenerative braking system as a second system where the two braking systems are linked to allow for simultaneously providing conventional and regenerative braking independently to the front and rear wheels of the vehicle.

A fuel cell system mounted on a vehicle includes a drive motor generating a driving force and regenerative power; an auxiliary machine consuming the regenerative power; and a controller. The controller determines that the vehicle is in a first state when the vehicle has a negative vehicle speed, a move forward request is given to the vehicle and an accelerator pedal is depressed or when the vehicle has a positive vehicle speed, the move backward request is given to the vehicle and the accelerator pedal is depressed. When a predetermined first condition including a condition that the vehicle is in the first state is satisfied, the controller performs an auxiliary machine consumption process that causes the auxiliary machine to consume the regenerative power that includes a required power for the drive motor calculated by using a depression amount of the accelerator pedal.

A brake system may include an actuation device, in particular a brake pedal; a first piston-cylinder unit with two pistons, in particular an auxiliary piston and a second piston, in order to supply brake circuits with a pressure medium via a valve device, wherein one of the pistons, in particular the auxiliary piston, can be actuated by means of the actuation device; a second piston-cylinder unit comprising an electric motor-powered drive, a transmission, and at least one piston in order to supply pressure medium to at least one of the brake circuits via a valve device; and a motor pump unit with a valve device in order to supply pressure medium to the brake circuits. The brake system may further include a hydraulic travel simulator which is connected to a pressure or working chamber of the first piston-cylinder unit.

An electric brake booster includes: a first pressure device, which generates brake fluid pressure via manipulation of a brake pedal; a second pressure device, which is connected to the first pressure device through a flow path at one side of the second pressure device, receives brake fluid pressure from the first pressure device, and receives driving power of a motor connected to another side of the second pressure device; a sensing unit mounted in the motor and measuring a displacement of the brake pedal and a rotation angle of the motor; and a buffer device connected to the second pressure device and preventing an increase in pressure of the brake pedal when the motor does not operate, in which motor rotation is controlled with a displacement of the brake pedal.

A vehicle control device includes a user-depressible portion that in some examples takes the form of a third foot pedal. The user-depressible portion may be depressed to varying degrees and then released to varying degrees. The degree and type of pedal movement is analyzed to determine one of a predetermined plurality of vehicle control functions that the drives wishes to perform.

This brake control device includes: an operation amount sensor which detects the brake operating member operation amount; front-wheel and rear-wheel actuators which generate braking force in front/rear wheels; front-wheel and rear-wheel sensors which detect the outputs of the front-wheel and rear-wheel actuators; and a controller which controls the front-wheel and rear-wheel actuators based on the operation amount and the outputs of the front and rear wheels. On the basis of the operation amount and/or the output of the rear wheels, the controller determines whether or not a long-term low-load state in which the friction member is continuously pressed against the rotary members of the rear wheels within a predetermined range over a long period of time is established. If so, the distribution ratio of the rear-wheel braking force to the total applied braking force is decreased compared to when a long-term low-load state is not determined to be established.

Multiple sensors are coupled to a first pin of a PSI5 transceiver to receive a sensor bus signal. A Manchester decoder is coupled to a second pin and a battery is coupled to a third pin. A comparator receives a first voltage that is proportional to a current on the sensor bus signal and a second voltage that is proportional to a base current on the sensor bus signal and sends a data output signal to the second pin. A sample-and-hold circuit captures a third voltage used to effect the second voltage responsive to a high value on a base current sampling signal. A base-current-renewal circuit detects edge transitions on the data output signal and when the data output signal has no edge transitions for a period of time greater than a gap time defined in a PSI5 standard, sets the base current sampling signal high.

A control device for a controllable brake booster of a braking system is configured to: establish a setpoint variable regarding a setpoint operation to be carried out with the aid of the controllable brake booster, under consideration of a provided specified variable regarding a setpoint pressure to be set in a partial volume of the braking system; establish a setpoint difference of the setpoint variable, under consideration of the specified variable and an actual variable regarding an actual pressure present in a subarea of the braking system, to establish a corrected setpoint variable taking the established setpoint difference into consideration; and output a control signal which corresponds to the established corrected setpoint variable to the controllable brake booster and/or to the power supply component of the controllable brake booster.
