  • Patent number: 10100750
    Abstract: A propulsion control system for a vehicle includes a driver pedal, a driver pedal position sensor that outputs a driver pedal position signal that indicates a position of the driver pedal, a memory that stores a first pedal map, and a processor that generates a torque request based upon the driver pedal position signal and the first pedal map. The first pedal map correlates a value of the driver pedal position signal to the torque request for a propulsion system in the vehicle and a first portion of the first pedal map near a traction limit has a first slope that defines the rate of change of the torque request to be less than the rate of change of the pedal position.

  • Patent number: 10035501
    Abstract: At a time of HV traveling entailing a load operation of an engine in a CD mode, an electronic control unit sets a required torque Tr* by using a map for a CS mode, in which the required torque Tr* is set to be lower than in a map for the CD mode, as at a time of the CS mode. Then, the electronic control unit control the engine and a motor for traveling in accordance with the required torque Tr*. Accordingly, a rise in the required torque Tr* can be suppressed compared to setting of the required torque Tr* using the map for the CD mode and a sense of high-rpm idling attributable to a rise in a rotation speed of the engine can be inhibited from being felt by a driver.

  • Patent number: 10035431
    Abstract: An electric vehicle includes front and rear wheels, a battery, an electric motor that drives at least one of the front and rear wheels, an accelerator, and a mode shift operator that is operated by a user in order to switch drive modes. The electric vehicle includes a driving force characteristics setter that sets, for each of the plurality of drive modes, driving force characteristics which are characteristics of an accelerator opening degree and a target motor driving force for the rotational speed of the electric motor. The electric vehicle further includes a controller which shifts up, according to an operation of the mode shift operator, the drive mode from a first drive mode to a second drive mode and which controls the target motor driving force according to the driving force characteristics. When a shift-down prohibition condition is met, the controller prohibits a shift down from the second drive mode to the first drive mode.

  • Patent number: 10029689
    Abstract: A control apparatus applied to a hybrid vehicle of the invention executes a regeneration control for charging a battery with electricity generated by a motor generator while applying regeneration braking force to the vehicle from the motor generator. The apparatus executes an enlarged regeneration control for charging the battery with the electricity generated by the motor generator while applying increased regeneration braking force to the vehicle from the motor generator when a target deceleration end position is set. The apparatus executes a control for controlling a vehicle speed to a speed equal to or smaller than an upper limit speed when a control execution request is generated. The apparatus forbids the enlarged regeneration control when the control execution request is generated and the vehicle speed is equal to or larger than a threshold vehicle speed smaller than the upper limit speed.

  • Patent number: 10023074
    Abstract: A transportation system with a non-rail-bound, electrically or diesel-electrically driven vehicle, has a two-pole overhead conductor system with contact wires forming supply and return conductors. The vehicle has a current collector for the supply of electrical energy through sliding contact with the contact wires. A video detector on the vehicle determines a position of the contact wires relative to the vehicle. Marking elements mark the position of the contact wires. The video detector is oriented for taking video images of the marking elements, and an evaluation unit recognizes from a recorded video image whether contact wires are present above the vehicle and, when they are present, determines their position relative to the vehicle. Through the improved recognition of the position of the vehicle relative to the overhead conductor the operational safety of the transportation system is improved.

  • Patent number: 10027141
    Abstract: A measurement unit (200) measures voltages and currents of battery cells (100). A battery control unit (400) calculates a present estimation value of a residual capacity of the battery cells (100) by integrating the currents. The voltages of the battery cells (100) are set to a reference voltage value V1 serving as a trigger of a process of correcting the estimation value of the residual capacity and an alarm voltage value Va which is a voltage higher than the reference voltage value. In addition, the battery control unit (400) continues discharge of all the battery cells (100), as it is, when an alarm condition in which a voltage of a minimum capacity cell is equal to or less than the alarm voltage value is not satisfied, and outputs a first signal when the voltage of the minimum capacity cell satisfies the alarm condition.
