A system for monitoring and controlling shopping cart usage comprises a wheel assembly that attaches to a shopping cart. In some embodiments the wheel assembly includes a wheel, a brake that can be activated to inhibit rotation of the wheel, a controller that controls the brake, a VLF receiver, and an RF transceiver. The RF transceiver may, for example, operate in a 2.4 GHz frequency band. In some implementations, the RF transceiver may be used to detect entry of the shopping cart into a checkout area of the store, and the VLF receiver may be used to detect that the shopping cart is exiting the store. The controller may activate the brake if the shopping cart attempts to exit the store without first passing through a checkout area.

A bicycle braking system includes a server, a portable device such as a smartphone, a display unit, a control unit, a power supply unit, a rotating electrical machine, and a bicycle. The portable device includes an image display unit, a braking condition transmitting unit, and a braking condition setting unit. The control unit regeneratively brakes the bicycle using the rotating electrical machine in accordance with the braking condition set by the braking condition setting unit. The braking system enables a non-user to set braking conditions for the bicycle and to perform braking based on the conditions set by the non-user.

A method includes applying a brake system of a multi-vehicle system using an onboard controller device and receiving grade input at the onboard controller device from a remote controller device. The grade input indicates a grade of a surface on which the multi-vehicle system is disposed. The method further includes starting movement responsive to receiving a speed command signal at the onboard controller device from the remote controller device. The movement started by initiating release of the brake system and/or generating tractive effort from a propulsion system of the multi-vehicle system stretches the multi-vehicle system. The method further includes, responsive to the movement reaching a designated speed, switching to a closed loop control process of controlling the movement based on one or more of the speed command signal or a brake command signal received at the onboard controller device from the remote controller device.

A robot has brake and accelerator actuating levers (9, 10) and a rotary actuator (12) between them. A drive ring (16) is fast with an actuator drive member (14) and between them they captivate a journal bearing (17) for the brake actuating lever (9) on which a return spring (19) acts. Advance of the lever is via a cam member (31) adjacent it. Wherever the output drive member (14) from the rotary actuator is turned, the cam member is rotated correspondingly. For brake application, the drive member (14) is driven, clockwise in FIG. 2. For brake release, and accelerator application, the drive member is driven back and the cam member is disengaged from the lever (9) with unidirectional freedom. The drive ring (16) is carried on a central ‘clutch’ member (35). The central member (35) is journalled in a fixed clutch member (36), which carries a clutch operating winding (38) for clutching together the central member (35) and an accelerator drive member (39) journalled on the central member. A central drive shaft (41) is fast with the accelerator drive member (39) and passes through the length of the rotary actuator. When the winding is energised, rotation of the output drive member (14) is transferred to this central drive shaft (41) for the accelerator actuating lever (10) as well.

The present disclosure provides a method and a device for vehicle parking control. The method includes following steps performed according to a predetermined time period until the vehicle stops at an end point: determining (101) a target position and a target speed when the vehicle arrives at the target position based on a current speed of the vehicle and a distance between a current position and the end point, the target position being on a road where the vehicle is located and in front of the vehicle; determining (102) a deceleration motion mode for the vehicle based on the current speed of the vehicle and the target speed; and performing (103) braking control for the vehicle in accordance with a vehicle braking strategy corresponding to the deceleration motion mode. The method can solve the problem in the related art associated with inaccurate vehicle parking control and uncomfortable experience.

The present invention provides a driving assist apparatus, a driving assist method, and a driving assist system capable of realizing driving assist in consideration of a delay in a driver's operation regardless of a configuration of a vehicle. A driving assist apparatus includes a standard running route acquisition portion configured to acquire a standard running route calculated based on curve information ahead of a vehicle that is acquired by an external world recognition portion, and an actuator control output portion configured to acquire a standard vehicle motion amount when the vehicle runs the standard running route, calculate an instruction that guides a motion amount of the vehicle toward the standard vehicle motion amount based on the standard vehicle motion amount and a current vehicle motion amount of the vehicle, and output the instruction to an actuator portion configured to provide at least one of a curving force and a braking force to the vehicle.
