A movable body control system includes: a movable body on which a user is capable of riding; a support device that supports a body of the user in a lying posture; a body detection device that detects a state of the user supported by the support device; a periphery monitor device that monitors a periphery of the support device; and a determination part that determines whether or not the movable body is capable of approaching the support device based on a detection result of the periphery monitor device. In the movable body control system, in a case where the body detection device detects that the user is in a predetermined state and the determination part determines that the movable body is capable of approaching the support device, the movable body approaches the support device.

Movable body control system

A control deviceof a rideable mobile bodydetermines a target speed of the rideable mobile bodyaccording to at least the steering operation by a rider, and controls the travel of the rideable mobile bodyaccording to the target speed. In the processing for determining a target speed, the target speed is restricted according to the positional relationship between a virtual wall set in a travel environment of the rideable mobile bodyand the rideable mobile body. Thus, the comfort of the rider is secured while the travel of the rideable mobile body is restricted by the virtual wall.

A vehicle includes a vehicle body frame, a vehicle body tilt sensor, a drive unit, and a seat. The vehicle body tilt sensor is provided at the vehicle body frame and detects a tilt angle of the vehicle body frame. The drive unit is coupled to the vehicle body frame and moves the vehicle body frame by inverted pendulum control based on the tilt angle detected by the vehicle body tilt sensor. The seat includes a seat body and a leg part. The seat is capable of being raised and lowered between a low position at which the leg part is in contact with a floor surface and a high position at which the leg part separates from the floor surface, and the seat is elastically coupled to the vehicle body frame. A seat tilt sensor which detects a tilt angle of the seat is provided at the seat.

A movable body control device controls a movable body which a worker who performs a work task at a workplace is capable of boarding and which is capable of traveling in a state where the worker is boarding. The movable body control device includes: an acquisition part that acquires, from a terminal device that is carried by the worker and that receives information which is input by the worker in accordance with the work task, information based on input information which is input by the worker in accordance with the work task; and a control part that controls a speed of the movable body based on the information which is acquired by the acquisition part.

The vehicle is provided with a lift unit includes a fixed base () supported by a vehicle body frame, a movable base () connected to a seat base supporting a seat (), and supported by the fixed base so as to be movable between a lowered position and a reference position higher than the lowered position relative to the fixed base, an engagement device () configured to selectively retain the movable base to the fixed base at the reference position, an electric lift mechanism () configured to move the movable base vertically relative to the seat base, and a control unit () controlling the engagement device and the electric lift mechanism.

An inverted pendulum vehicleis provided with a display unitfor illuminating a floor surfacesurrounding a vehicle body thereof, and a display control unitfor controlling an illumination pattern of the display unit according to an inclination angle detected by an inclination detection unit

Inverted pendulum vehicle

An inverted pendulum control type moving body is provided with: a first driving portion that moves a host moving body at least in a forward/backward direction; a supporting portion that supports the inverted pendulum control type moving body so that it stands independently in a state of being in contact with the ground; an operation portion that switches between the ground contact state and a ground separation state of the supporting portion; and a control portion that, when the operation portion switches the state of the supporting portion from the ground contact state to the ground separation state, controls operation of the first driving portion so that a forward/backward direction tilt angle of the inverted pendulum control type moving body approximates a target tilt angle in the ground contact state.

Inverted pendulum control type moving body

A discharge control apparatus in an electric motorcycle includes a main battery; a motor driven based upon electric power supplied from the main battery and a lighting device that is a load other than the motor for consuming electric power. A BMU determines a remaining capacity of the main battery. A control member performs a discharge control of the main battery for supplying electric power to the motor and the lighting device. The BMU and the control member allow the discharge of the main battery until the remaining capacity becomes a threshold value higher than zero. When the control member receives an instruction of checking a deterioration state of the main battery from an external checking device, the control member performs a discharge of the main battery until the remaining capacity reaches zero, and then, allows the main battery to be fully charged so as to determine a chargeable capacity.

Discharge control apparatus for electric vehicle

An apparatus which estimates the temperatures of a motor without using a temperature sensor can achieve overheat protection by proper control. In an example, a heat generation amount calculation section calculates a heat generation amount of a motor. A current upper limit map has a current upper limit value corresponding to a temperature estimated value and a ratio map has a ratio corresponding to the temperature estimated value. A lower one of limited current values, determined using the two maps, controls energization of the motor. The heat generation amount calculation section includes a heat generation correction term, and a heat radiation correction term for calculating a function of the difference between the integrated value of the heat generation amount and a motor ambient temperature. If the ambient temperature becomes equal to or higher than a comparison temperature, then the heat generation amount is calculated without the heat radiation correction present.

Overheat protection apparatus

A removable steering angle sensor for a motor-driven power steering apparatus for use in a vehicle intended for rough road use. The handlebar of the vehicle is disposed on an upper portion of a steering shaft, and a motor-driven power steering apparatus, including a power assist portion as an actuator unit, is disposed in a middle portion of the steering shaft. The steering angle sensor for detecting a steering angle is disposed on one end of the steering shaft, or more specifically, on a lower end portion of an output shaft, or a leading end portion of an output shaft. During maintenance, this arrangement provides for easy removal and installation of the steering angle sensor.
