Problems solved by technology

[0003] In addition, in the parking assist device, when assisting the entry or exit of the vehicle into or out of the parking space, the steering wheel is operated by the automatic control of the steering device without the driver's steering operation. During automatic control, the load on the steering device increases and the temperature of the device tends to rise

Embodiment Construction

[0032] Below, according to Figure 1 to Figure 12 , an embodiment of the parking assist device will be described.

[0033] figure 1 The illustrated vehicle is provided with a steering device 2 for operating steered wheels 1 for adjusting the traveling direction of the vehicle. The steering device 2 operates the steered wheels 1 by a driver's steering operation, and has a function of assisting the driver's steering operation by an electric motor 2 a. It should be noted that this device 2 is independent of the presence or absence of a driver's steering operation, and the operation of the above-mentioned steered wheels 1 can also be performed only by the electric motor 2 a. The driver's seat of the vehicle is provided with a display panel 3 that displays driving-related information and the like and receives various operations from the driver, and a speaker 4 that notifies the driver of driving-related information or warnings by sound.

Abstract

When assisting the entry or exit of a car into / from a parking space by means of the automatic control of a steering device (2), calculations are performed such that the rise in temperature of the motor (2a) of the device (2) caused by the execution of automatic control is larger the larger the excess space (excess length) with respect to the size of the vehicle. Moreover, the predicted temperature of the motor (2a), which will rise as a result of the aforementioned automatic control, is calculated by adding that rise in temperature to the current value for the temperature of the motor (2a). If the predicted temperature is equal to or higher than the determined value, the execution of the aforementioned automatic control is disabled, and if the predicted temperature is lower than the determined value, the execution of the aforementioned automatic control is enabled.

Description

technical field [0001] The invention relates to a parking assistance device. Background technique [0002] Vehicles such as motor vehicles are known to be equipped with a parking assist device that assists when parking the vehicle in a predetermined parking space or when starting the vehicle from the parking space. In such a parking assist device, instead of actuating steering wheels of the vehicle for entering or exiting the vehicle into or out of the parking space by the driver's steering operation, automatic control of the steering device is performed. By performing automatic control of the steering device, even if the driver does not perform a steering operation, the steering wheel for entering or exiting the vehicle relative to the parking space can be operated, thereby realizing the entry or exit of the vehicle relative to the above-mentioned parking space. Auxiliary exit. [0003] In addition, when assisting the entry or exit of the vehicle into or out of the parkin...
