Embodiment approach 1

[0045] figure 1 , figure 2 , image 3 , Figure 4 It is a drawing for explaining the electric vehicle 11 according to Embodiment 1 of the present invention. figure 1 is a schematic configuration diagram of the electric vehicle 11, figure 2 It is a time chart of the traveling control information indicating the direction of the speed of the traveling target in translation and the magnitude of the speed in the vertical direction. image 3 is a perspective view of the electric vehicle 11 according to Embodiment 1, Figure 4 It is a plan view of the electric vehicle 11 according to the first embodiment.

[0046] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the electric vehicle 11 according to Embodiment 1 is an electric wheelchair that moves by the operation of a driver seated on the seat portion 13 . Also, for ease of understanding, a vehicle coordinate system Σr (with three mutually orthogonal x r axis, y r axis, z r axis coordinate system). by...

Embodiment approach 2

[0103] Figure 17 , Figure 18 It is a drawing used for explaining the electric vehicle 51 which concerns on Embodiment 2 of this invention, Figure 17 is a perspective view of the electric vehicle 51, Figure 18 is a plan view of the electric vehicle 51 .

[0104] Next, regarding this second embodiment, while referring to the attached Figure 1 Differences from Embodiment 1 will be described. Such as Figure 17 , Figure 18 As shown, the electric vehicle 51 is an electric transport trolley that is pushed (or pulled) by a driver to move.

[0105] The electric vehicle 51 is equipped with: a body part 52; a handle part 53, which is an operation input part for detecting an input operation direction and an operation amount; Rotate travel target speed), generate travel control information according to the travel target speed; the control unit 16. In addition, the handle portion 53 is a driver contact portion provided on the vehicle body portion 52 .

Abstract

An electric vehicle (11) travels by driving actuators (32) and comprises: a measurement unit for measuring the external environment of or the internal environment of the electric vehicle (11); a notifying unit (21) for sending, based on the information measured by the measurement unit, a vibration speed signal that is a signal representing a periodically fluctuating speed; a travel information generation unit (15) for calculating a travel target speed on the basis of an operation direction and an operation amount that are input by the driver of the electric vehicle (11) and generating travel control information for controlling the actuators (32) on the basis of the travel target speed; and a control unit (16) for controlling the actuators (32) on the basis of the travel control information. After receiving the vibration speed signal, the travel information generation unit (15) regenerates the travel control information by combining the travel target speed with the vibration speed signal.

Description

technical field [0001] The present invention relates to an electric vehicle such as an electric wheelchair that is moved by a driver, or an electric transport cart that moves in parallel with the driver, and a control method thereof. Background technique [0002] As a vehicle such as a wheelchair or a carrying cart, there is currently provided an electric vehicle that moves by the force of a drive unit. [0003] Among electric vehicles, there is a vehicle having a notification unit that notifies the driver of the exhaustion of the battery unit for supplying electric power to the driving unit by sound or light. In addition, there is also an electric vehicle having a notification unit that, when an obstacle sensor detects an obstacle in the direction of travel, notifies the driver of the information in the form of sound or light. [0004] However, in the case where information such as battery exhaustion notice or obstacle detection is notified to the driver in the form of lig...
