摘要： A control device for electric motor vehicle using the motor as the traveling driving source and configured to decelerate by a regenerative braking force from the motor detects the accelerator operation amount, calculates the disturbance torque estimated value, and detects or estimates the resistance component unrelated to the gradient from the vehicle state. The control device for electric motor vehicle corrects the disturbance torque estimated value according to the detected or estimated resistance component unrelated to the gradient. The motor is controlled on the basis of the motor torque command value. When the accelerator operation amount is equal to or less than the predetermined value and the electric motor vehicle is just before the stop of the vehicle, the motor torque command value converges to the corrected disturbance torque estimated value in conjunction with the reduction of the rotation speed of the motor.

摘要： A vehicle brake control device includes an electric motor controlled based on a target energization amount calculated based on an operation amount (Bpa) of a braking operation member. Based on the operation amount (Bpa), it is determined whether or not an inertia compensation control for compensating for the influence of the inertia of a brake actuator is necessary. When the inertia compensation control is determined to be necessary, an inertia compensation energization amount for compensating for the influence of the inertia of the brake actuator is calculated based on a time-series pattern set in advance based on the maximum response of the brake actuator. Based on the inertia compensation energization amount, the target energization amount is calculated. The vehicle brake control device is thus able to generate a braking torque that appropriately compensates for the influence of the inertia of the entire device including the inertia of the electric motor.

摘要： A braking-driving force control system is provided in which erroneous vehicle speed detection may be avoided even when a frictional braking power is generated during rotation of an output shaft coupled to an electric driving motor as driving source. When only regenerative braking force is being generated as braking force while the vehicle is traveling, the braking force and the driving force are controlled based on an output shaft side vehicle speed calculated from the rotational state of an output shaft of a driving source, and when the frictional braking power is being generated while the vehicle is traveling, the braking force and the driving force will be controlled based on a wheel side vehicle speed representing the vehicle speed calculated from the rotational state of the vehicle wheel.

摘要： A brake control apparatus includes: a master cylinder that outputs a brake fluid at a master pressure; a master pressure changing device that can change the master pressure irrespective of an operation of a brake pedal; a brake actuator; and a control unit that executes antilock control by reducing a brake pressure of a target wheel. Modes of the antilock control include a normal mode and a pseudo mode. In the pseudo mode, the control unit operates the master pressure changing device such that the master pressure obtains a target value of the brake pressure of the target wheel, and changes the brake pressure of the target wheel in an interlocking manner with the master pressure. When the normal mode is unavailable, the control unit executes the antilock control in the pseudo mode.

摘要： A method controls regenerative braking of a vehicle equipped with regenerative brakes and with a separate braking apparatus. The method is designed to generate a regenerative braking setpoint as a function of a braking request signal coming from a driver pedal of the vehicle, according to a first setpoint generation mode. The method includes receiving a flag signal coming from an active safety system of the vehicle, detecting value changes of the received flag signal, when the received flag signal changes value to take a value corresponding to activation of regulation by the active safety system, incrementing a counter value, and comparing the counter with a threshold. When the counter reaches the threshold, a control signal is formed to end the generation of the regenerative braking setpoint according to the first calculation mode and to impose generation of the regenerative braking setpoint according to a second calculation mode.

摘要： A control apparatus mounted on a railcar including a plurality of wheelsets includes: a torque basic value setting portion configured to set a basic value of torque applied to each of the plurality of wheelsets; an adhesion determining portion configured to determine whether or not each of the plurality of wheelsets adheres to a rail; and a torque correcting portion configured to correct the basic value of the torque to obtain a corrected value that is smaller than the basic value. The plurality of wheelsets includes one or more specific wheelsets and one or more general wheelsets other than the specific wheelsets. The torque correcting portion calculates the corrected value of the torque, applied to the general wheelset, in accordance with a first rule and calculates the corrected value of the torque, applied to the specific wheelset, in accordance with a second rule different from the first rule.
