    Abstract: The brake device for a vehicle generates two master pressures by controlling one single servo pressure to accurately control braking force. The pressure increasing characteristic is set based on the first pressure increasing characteristic obtained from the relationship between the servo pressure and the first master pressure upon increasing the servo pressure and the second pressure increasing characteristic obtained from the servo pressure and the second master pressure. The pressure decreasing characteristic is set based on the first pressure increasing characteristic obtained from the relationship between the servo pressure and the first master pressure upon decreasing the servo pressure and the second pressure decreasing characteristic obtained from the servo pressure and the second master pressure. Thus, the total braking force of the brake device is the sum of a braking force generated by the first master pressure and a braking force generated by the second master piston.

  • Patent number: 9248822
    Abstract: A variable control apparatus and method of the amount of regenerative braking of a vehicle using a paddle shift are provided. The method includes sensing, by a controller, positive (+) and negative (?) shifting in a manual mode based on a signal from a shift-operating unit during regenerative braking with a drive (D) gear engaged while the vehicle travels. A regenerative braking torque map that corresponds to a selected gear is selected based on the signal from the shift-operating unit. In addition, regenerative braking of a driving motor is adjusted based on the torque value calculated from the selected regenerative braking torque map.

  • Patent number: 9238412
    Abstract: A method of operating a vehicle having a friction braking system and a regenerative braking system is presented here. The method determines a regenerative torque capacity, calculates a desired regenerative torque amount for the braking system, detects that the desired regenerative torque amount exceeds the regenerative torque capacity by at least a threshold amount, and controls actuation of the friction braking system in response to the detecting. Another operating method determines a coastdown torque capability of the vehicle, calculates a desired coastdown torque amount, detects that the desired coastdown torque amount exceeds the coastdown torque capability by at least a threshold amount, and controls actuation of the friction braking system in response to the detecting.

  • Patent number: 9211871
    Abstract: A vehicle and a method for controlling regenerative braking may utilize the maximum available regenerative braking torque for some time during a braking event. As the vehicle speed and/or powertrain torque decreases, the regenerative braking torque is controlled to deviate from the maximum. The point at which the regenerative braking torque deviates from the maximum is chosen based on the level of vehicle deceleration. The regenerative braking torque is then smoothly blended out until it reaches zero. The regenerative braking torque is brought to zero when the vehicle speed is very low, thereby eliminating the inefficiencies associated with operating a motor at a very low speed.

  • Patent number: 9193337
    Abstract: Brake hydraulic pressure is appropriately prevented from becoming lower than a reference brake pressure for holding control. When a physical amount correlating with the rotational speed of an electric motor has become higher than or equal to a predetermined value, an HSA start reference pressure setting unit sets an HSA start reference pressure to a value higher than a reference brake pressure, and if the HSA start reference pressure at a time when a driver required fluid pressure has become lower than the HSA start reference pressure is higher than the reference brake pressure, an HSA required fluid pressure setting unit sets an HSA required fluid pressure at a time when the driver required fluid pressure has become lower than the HSA start reference pressure to a value higher than the reference brake pressure.

  • Patent number: 9174621
    Abstract: Systems and methods are described for providing magnetic biasing of a carriage in context of linear guides. In one embodiment, a robotic mechanism is configured to travel on a platform assembly within a structural context. The platform assembly transports a carriage in a Z direction, and the carriage transports the robotic mechanism in an X direction. The carriage moves in the X direction along rails (e.g., and/or other types of linear guides) in a substantially floating or unbiased manner. For example, one or more alignment features on the carriage are in communication with the rails to allow the carriage to move relatively freely within an alignment region defined by the alignment features. When the carriage reaches its desired X location, magnetic features bias the carriage into a substantially accurate, secure, and repeatable position.
