摘要： Provided is a high-torque low-noise rotary electric machine.
In a rotary electric machine 200, a jumper conductor 233b having a normal slot pitch connects slot conductors 233a by striding slots 237 with a slot pitch "Np = N (= 6)" in one of coil ends 241 and striding slots 237 with a slot pitch "Np = N (= 6)" in the other coil end 241, assuming that the number of slots per pole is set to "N (= 6)." The jumper conductor 233b having an irregular slot pitch connects the slot conductors 233a by striding slots 237 with a slot pitch "Np = N + 1 (= 7) " in one of the coil ends 241 and striding slots 237 with a slot pitch "Np = N - 1 (= 5)" in the other coil end 241, assuming that the number of slots per pole is set to "N (= 6)." The stator winding 238 has a plurality of slot conductor groups 234 consisting of a plurality of slot conductors 233a having the same phase.

摘要： The present disk brake includes a carrier fixed to a non-rotatable portion of a vehicle, a caliper attached to this carrier and including a piston configured to press an inner brake pad, a slide pin fixed to any of the carrier and the caliper and configured to allow the caliper to slidably move relative to the carrier in an axial direction of a wheel, and a driving mechanism including an electric motor and a speed reduction mechanism and configured to transmit a driving force of the electric motor to the piston via the speed reduction mechanism. At least a part of the driving mechanism is disposed on an extension of an axis of the slide pin. This configuration can prevent an increase in the size of the present disk brake, thereby improving the mountability thereof onto a vehicle.

摘要： An object of the present invention is to appropriately control a clearance amount by correcting an estimation error of a contact position caused by a delay time difference between output signals of sensors, and to establish both improvement of fuel efficiency due to prevention of drag of a brake pad during non-braking and reduction in response time during braking.
A brake system includes a brake disc, a brake pad, a piston, a drive mechanism, a position sensor that detects a position of the piston, a thrust sensor that detects a thrust by which the brake pad presses the brake disc, and a brake control unit that adjusts a braking force by controlling the drive mechanism. The brake control unit includes a contact position computation unit that computes a contact position at which the brake pad and the brake disc come in contact with each other based on output signals of the position sensor and the thrust sensor, a position error computation unit that computes a position error of the contact position based on a delay time difference between the output signals of the position sensor and the thrust sensor, and a contact position correction unit that corrects the contact position obtained by the contact position computation unit by using the position error.

摘要： The present invention provides a technique to accurately recognize a position of a vehicle even in a vicinity of a branch road or a junction road, neither of which is included in map data. The present invention provides a vehicle control device. When a vehicle is traveling on a road that is not described in map data, the vehicle control device is configured to determine whether or not the vehicle is traveling on a junction road or a branch road, based on a positional relationship between a position of the vehicle and a starting point of the junction road or a starting point of the branch road.

摘要： The present invention provides a control apparatus for an electric vehicle that can prevent a vehicle from losing the stability because a rear wheel is locked first or prevent the drivability from reducing because a front wheel is locked early. A control apparatus outputs an instruction to generate a first regenerative braking force corresponding to a regenerative braking force on an electric motor when a signal regarding a return of a pressed accelerator pedal is input from an accelerator pedal sensor. The accelerator pedal sensor is configured to detect a physical amount regarding a stroke of the accelerator pedal of the electric vehicle. The control apparatus outputs an instruction to generate a brake actuation braking force on a wheel when a signal regarding pressing of a brake pedal is input from a brake pedal sensor. The brake pedal sensor is configured to detect a physical amount regarding a stroke of the brake pedal of the electric vehicle. The control apparatus outputs, to the electric motor, an instruction to reduce a total value of the first regenerative braking force and the brake actuation braking force by a braking force corresponding to a second regenerative braking force, which is a regenerative braking force smaller than the first regenerative braking force, when an output value lower than a predetermined speed is input from a vehicle body speed detection sensor. The vehicle body speed detection sensor is configured to detect a physical amount regarding a vehicle body speed of the electric vehicle.
