    Abstract: In general, the subject matter described in this specification can be embodied in methods, systems, and program products for performing vehicle traction control. Time intervals between points of rotation of a rotating vehicle output shaft are measured. Indicators of shaft rotation rate are generated using, for each generated indicator, a set of one or more of the time intervals. The generated indicators of shaft rotation rate are used to determine a value indicative of a rate of change of shaft rotation rate. An indicator of a maximum allowable output shaft rotation rate is computed. A current indicator of output shaft rotation rate is determined to exceed the maximum allowable output shaft rotation rate. In response to determining that the current indicator exceeds the maximum allowable output shaft rotation rate, a signal to trigger application of a traction control mechanism is output.

A high pressure accumulator device (20) can be connected with the respective high-pressure side hydraulic connection (6a, 6b) and, simultaneously, the respective low-pressure side hydraulic connection (6b, 6a) can be connected with a hydraulic balancing device (30). A valve device (50) is provided for this simultaneous connection. The valve device (50) is a hydraulically controlled shuttle valve device (51) connected to the two hydraulic connections (6a, 6b), the high pressure accumulator device (20) and the hydraulic balancing device (30).

  • Patent number: 10151254
    Abstract: An engine system includes: a hydraulic valve stop mechanism configured to switch states of an intake valve and exhaust valve of a same stopped cylinder; a hydraulic pressure changing device configured to change hydraulic pressure supplied to the valve stop mechanism; and a valve control portion configured to control the hydraulic pressure changing device. When a return from a reduced-cylinder operation to an all-cylinder operation is requested, and an engine revolution is less than a reference revolution, the hydraulic pressure is changed such that opening of one of the valves of the stopped cylinder able to restart at an earlier stage is first restarted. When the return is requested, and the engine revolution is not less than the reference revolution, the hydraulic pressure is changed such that opening of the exhaust valve of the stopped cylinder is restarted before opening of the intake valve.

  • Patent number: 10150369
    Abstract: Certain embodiments of the present disclosure describe a differential assembly for allowing a vehicle to switch between two-wheel drive and four-wheel drive. The differential assembly includes a bearing assembly positioned between a race gear and output hubs. An armature plate is rotationally coupled to the bearing assembly and a clutch plate is positioned to engage the armature plate. A biasing member biases the clutch plate to engage the armature plate and allow the bearing assembly to transmit torque between the race gear and output hubs. When electricity is provided to an electromagnet, the electromagnet exerts a magnetic force on the clutch plate that is sufficient to overcome the bias of the biasing member so the clutch plate does not engage the armature plate and the bearing assembly does not transmit torque from the race gear to the output hubs.

  • Patent number: 10137786
    Abstract: Appropriate tuck-in suppression control is enabled in a vehicle configured to carry out regeneration enhancement control. A predictive deceleration support control unit is configured to set a position at which the vehicle is predicted to finish deceleration as a target deceleration end position, and guide a driver to release an accelerator pedal so that the deceleration of the vehicle is finished at the target deceleration end position, to thereby carry out regeneration enhancement control under a state in which the accelerator pedal is released so as to generate a larger deceleration than in a normal state. The predictive deceleration support control unit is configured to read a tuck-in control flag from a brake ECU, and stop the regeneration enhancement control when the tuck-in suppression control is being carried out.

    Abstract: An electric vehicle drive system includes first and second electric motors, first and second torque limiters and a torque splitter. The first and second torque limiters correspond to the first and second electric motors, respectively, and generate respective first and second maximum torques. The torque splitter receives a first input that includes at least a total torque request for the first and second electric motors and the first and second maximum torques and generates at least respective first and second torque requests for the first and second electric motors, wherein the torque splitter is configured to direct a torque request to the second motor only if the first maximum torque is less than a threshold. The torque splitter may generate a zero second torque request if a motor speed of the first electric motor exceeds a threshold.
