A pedal assembly includes a housing, a spring arm member, a pedal arm, a spring carrier, and a spring guide member. The spring arm member is coupled to the housing. The pedal arm has a hub portion and an opposite pedal pad. The hub portion is pivotally retained in the housing by the spring arm member at the hub portion. The spring carrier is coupled to the pedal arm and to the spring arm member. The spring carrier has at least one spring positioned to provide a first pedal effort force to the pedal arm at a first amount of predetermined travel of the pedal arm. The spring guide member contacts a second at least one spring from the pedal arm when the pedal arm exceeds a second amount of predetermined travel of the pedal pad. The at least one spring provides a second pedal effort force.

The capacitor-based power sources (9A, 9B) are recharged by a hub generator, a regeneration power source (32).

The present disclosure discloses a foldable pedal apparatus for a vehicle in which a pedal pad 210 protrudes to be exposed to the interior of a vehicle and pop up toward a driver in a manual driving mode in which the driver is actively involved in driving, in which the pedal pad 210 is inserted into a footrest panel 10 such that exposure toward the driver is blocked in a hide state in an autonomous driving mode, and which may generate a signal relating to a pedal function by operating the pedal pad 210 by pressure through the pressure-operated pedal assembly 200 in a pop-up state.

An operation control method of a foldable pedal apparatus, is capable of controlling an operation of the foldable pedal apparatus such that, when a starting-off state is changed to a starting-on state, a foldable brake pedal is popped up first, and then a foldable accelerator pedal is popped up with a time difference, and when the starting-on state is changed to the starting-off state, the foldable accelerator pedal is hidden first, and then the foldable brake pedal is hidden with a time difference.

A method of conducting a diagnostic test to determine leakage within a brake system includes first providing a brake system having a plunger assembly including a housing defining a bore therein. The plunger assembly includes a piston slidably disposed therein such that movement of the piston pressurizes a pressure chamber when the piston is moved in a first direction. The pressure chamber of the plunger assembly is in fluid communication with an output, and wherein the plunger assembly further includes an electrically operated linear actuator for moving the piston within the bore. The linear actuator of the plunger assembly is actuated to provide pressure at the output of the plunger assembly at a first predetermined level. The pressure at the output of the plunger assembly is held for a predetermined length of time. The method further includes determining whether conditional criteria has been met indicating a leakage within the brake system.

A vehicle pedal emulator assembly comprising a housing and a sleeve both defining an interior cavity. The sleeve is adapted for sliding movement in the interior cavity of the housing. Respective first, second, third, and fourth springs located in opposed ends of the interior cavity of the housing are compressible in parallel in response to the sliding movement of the sleeve in the interior cavity of the housing. The first and second springs surround the shaft and extend between one end of the housing and one end of the shaft. The third and fourth springs extend between one end of the sleeve and the other end of the sleeve. The combination of an inductive sensor and a Hall Effect sensor are adapted for measurement of the position of the sleeve relative to the housing.

A method for detecting a resistance on a brake pedal of a brake system, in which a brake pedal is pulled by an actuator, in which an ease of movement of the brake pedal is determined during operation of the actuator, wherein a resistance is detected as soon as the ease of movement is no longer clearly determined, and a method for controlling an actuator, a computer program product, control unit or system comprising a plurality of control units, and a corresponding device.

A method for checking functionality of a motor vehicle braking system. The braking system has a main module, including: hydraulically actuatable wheel brakes, pairs being assigned to respective brake circuits; at least one electrically actuatable wheel valve per wheel brake sets wheel-specific brake pressures; a pressure provision device actively builds up pressure in the wheel brakes; a pressure-medium reservoir at atmospheric pressure, and an auxiliary module, which has for each of two wheel brakes: a pressure sensor for measuring pressure in a wheel brake line; an open when deenergized isolating valve in the wheel brake line; a pump. At least one variable is measured to assess functionality of the braking system. Using least one acceptance criterion, and checked whether the variable satisfies the acceptance criterion. Determining at least one variable representing the viscosity of the brake fluid, and the at least one acceptance criterion depends on a variable representing viscosity.

The invention relates to a control device for controlling an engine driven transport apparatus. The control device comprises a fitness apparatus having a base part and at least one movable part movable with respect to the base part for enabling a user to perform a physical exercise. The control device further comprises a sensor device for sensing a degree of physical exercise. The control device is arranged for controlling engine power of an engine of the transport apparatus at least partly based on the sensed degree of physical exercise. The fitness apparatus comprises a flywheel rotatably connected to the base part. The fitness apparatus is arranged for setting the flywheel into motion by means of at least one of the one or multiple movable parts. The sensor device is arranged to sense the degree of performed physical exercise at least partly by sensing a degree of motion of the flywheel.

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.
