Embodiment Construction

[0096] refer to Figure 1a and Figure 1b , a vehicle 1 , embodied here as a heavy duty truck 1 , is disclosed for which a system 100 for positioning the vehicle 1 at a charging station 200 of the type disclosed in this disclosure is beneficial. However, the system 100 may also be implemented in other types of vehicles, such as in buses, light trucks, passenger cars, marine applications, etc., which require charging. The vehicle 1 is an electric vehicle, such as a fully electric vehicle or a hybrid vehicle, that includes a battery 10 and an electric machine or engine 20 , referred to herein as an electric machine powered by the battery 10 . The vehicle 1 is configured to be charged by the charging station 200 . exist Figure 1a and Figure 1bIn the example, charging is carried out by means of a power transmitter 210, which is arranged on the charging station 200 and is configured to transmit power to the power receiver 30 of the vehicle 1, but charging can also be carried ou...

Abstract

The invention relates to a system for positioning a vehicle at a charging station. A system (100) for positioning a vehicle (1) at a charging station (200) comprises: a wireless communication device (110) comprising a first communication device (112) configured to wirelessly communicate with a second communication device (114) over a wireless protocol; a vehicle positioning device (120) includes a transmit antenna (122) configured to transmit a detection signal (126) and a receive antenna (124) configured to receive the detection signal. The transmission of the detection signal by the transmitting antenna and / or the detection of the detection signal by the receiving antenna is controlled to determine an angle (alpha) between the transmitting antenna and the receiving antenna, which angle is used to guide the vehicle to a predetermined position (300) of the charging station. The first communication device includes one of a transmit antenna and a receive antenna of the vehicle positioning device.

Description

technical field [0001] The present invention relates to a system and method for positioning a vehicle at a charging station. The invention further relates to a computer program comprising program code means for carrying out the method. Background technique [0002] Vehicles typically include an engine for propelling the vehicle. The engine may be powered in various ways, such as by liquid or gaseous fuel in an internal combustion engine, or by electricity in an electric machine or electric motor. Furthermore, hybrid solutions exist, in which the vehicle is propelled by both an internal combustion engine and an electric machine. Either way, the motor can be powered using a battery that needs to be charged periodically. [0003] A common solution for charging the battery is by being connected by a wire to a power source, such as eg a plug from the mains. Typically, the vehicle is parked at a parking / charging point that provides this charging capability, and the driver or o...
