Abstract: An autonomous driving apparatus that executes an autonomous driving control of a vehicle is provided. The autonomous driving apparatus includes a tutorial switch and a controller. The controller is configured to: determine whether or not the autonomous driving control can be started; and determine whether or not a tutorial can be started, the tutorial being an explanation of an operation by a driver required for switching from the autonomous driving control to manual driving. A determination condition for determining that the tutorial can be started is less likely to be met than a determination condition for determining that the autonomous driving control can be started. The tutorial is started when the tutorial switch is in ON state and the controller determines that the tutorial can be started.

Abstract: A path determination apparatus according to this disclosure includes a gate selecting unit that, when a vehicle is to pass through a tolling station having a plurality of gates, selects a gate to pass through from among the plurality of gates. The gate selecting unit is configured to make a judgement as to whether or not a road which the vehicle travels on until passing through the tolling station is an expressway, as one conditional judgement for selecting the gate to pass through.

Abstract: A parking assistance apparatus includes a display unit that displays an image of a scene behind a host vehicle. At least when the host vehicle moves forward or when the host vehicle is stopped, the display unit displays an indication including a plurality of kinds of trajectories along which the host vehicle is able to back up from a point at which the host vehicle is currently positioned, in a manner such that the indication is superimposed on the image of the scene behind the host vehicle.

Abstract: In a vehicle remote operating system remotely operating a host vehicle VM from a portable terminal 200, a main control unit 112 of an ECU 110 of an in-vehicle device 100 determines an dispatch position of the host vehicle VM on the basis of a parking position of the host vehicle VM and a position of a user U who intends to board the host vehicle VM. Due to this, it becomes possible to dispatch the host vehicle VM according to the parking position of the host vehicle VM and the position of the user U, and convenience is improved in dispatch operation and boarding of the host vehicle VM.

Abstract: A high yield ratio-type, hot rolled high strength steel sheet excellent in both formability and spot weldability, containing not less than 5% of retained austenite, and a process for producing the same are provided. The steel sheet contains 0.05 to less than 0.15% by weight or 0.15 to less than 0.30% by weight of C, 0.5 to 3.0% by weight of Si, 0.5 to 3.0% by weight of Mn, more than 1.5 to 6.0% by weight of Si and Mn in total, not more than 0.02% by weight of P, no more than 0.01% by weight of S, and 0.005 to 0.10% by weight of Al, the balance essentially being Fe, and is composed of three phases of ferrite, bainite and retained austenite as a microstructure, and having a ratio (V.sub.F /d.sub.F) of ferrite volume fraction (V.sub.F) to ferrite grain size (d.sub.F) of not less than 20 (not less than 7 in case of 0.15 to less than 0.30% by weight of C), a volume fraction of retained austenite having grain sizes of not more than 2 .mu.

Abstract: A hot rolled steel sheet with a high strength and a distinguished formability, and a process for producing the same are disclosed. The steel sheet comprises 0.15 to 0.4% by weight of C, 0.5 to 2.0% by weight of Si, and 0.5 to 2.0% by weight of Mn, the balance being iron and inevitable impurities, and has a microstructure composed of ferrite, bainite and retained austenite phases with the ferrite phase being a ratio (V.sub.PF /d.sub.PF) of polygonal ferrite volume fraction V.sub.PF (%) to polygonal ferrite average grain size d.sub.PF (.mu.m) of 7 or more and the retained austenite phase being contained in an amount of 5% by volume or more on the basis of the total phases. The steel sheet can be produced with a high productivity and without requiring special alloy elements.
