  • Patent number: 12120860
    Abstract: The present disclosure is directed to achieve greater space efficiency. A wiring module (A) includes a first transmission line (20), and a noise shielding member (40) that has a sheet shape and is arranged along the first transmission line (20). The noise shielding member (40) has a thickness of 100 ?m to 600 ?m. Since the noise shielding member (40) has a sheet shape, and thus the space for arranging the noise shielding member (40) can be made smaller, it is possible to achieve greater space efficiency. Since the noise shielding member (40) has a thickness of 100 ?m to 600 ?m, it is possible to obtain a high noise shielding effect.

  • Patent number: 11718181
    Abstract: A vehicle includes a regenerative generator on a front wheel. A braking control device includes an actuator that applies a front wheel torque and a rear wheel torque, and a controller that individually adjusts the front wheel torque and the rear wheel torque. The controller is configured to determine the front wheel torque and the rear wheel torque to zero when a regenerative braking force Fg generated by the regenerative generator has not reached a maximum regenerative force Fx which is a generatable maximum value. On the other hand, the controller is configured to increase the rear wheel torque from zero before increasing the front wheel torque from zero when the regenerative braking force Fg reaches the maximum regenerative force Fx.
