Abstract:
A device for adjusting a vehicle speed when a roof of a convertible vehicle is open or closed is disclosed. According to the present invention, a device for adjusting a vehicle speed when a roof of a convertible vehicle is open or closed comprises: a sensor unit for generating traveling state information indicating a traveling state of the convertible vehicle; a control unit for extracting target traveling state information of the convertible vehicle corresponding to a roof open/closed preparation state of the convertible vehicle according to an open/closed input for the roof of the convertible vehicle and outputting a roof open/closed control signal if a result of comparing the traveling state information with the target traveling state information satisfies a predetermined roof open/closed operation condition; and an open/closed performing unit for opening or closing the roof of the convertible vehicle by performing an operation through the roof open/closed control signal, thereby having an advantage of maximally improving vehicle and driver stability when the roof is open or closed.
Abstract:
The invention relates to a method for determination of at least one reference value which indicates how a vehicle's speed is to be influenced and which can be used to control at least one control system in a vehicle. The invention is characterised by performing the steps of: - making a first prediction v pred_ Tnew_ret and a second prediction v pred_ Tnew_acc of a vehicle speed along a horizon, said first prediction based on an engine torque T ret which retards the vehicle as compared with a conventional cruise control, and said second prediction based on an engine torque T acc which accelerates the vehicle as compared with a conventional cruise control; - comparing said respective first prediction v pred_ Tnew_ ret and second prediction v pred_ Tnew_ acc of the vehicle speed with a lower limit value v min and/or an upper limit value v max which delineate a range within which the vehicle's speed should be, with an offset v 0ffset added to said lower and/or upper limit values v min and v max if the vehicle is in a route segment which comprises a steep hill; and - determining at least one reference value based on at least one of said respective comparisons and said first prediction v pred_ Tnew_ ret and second prediction v pred_ Tnew_ acc of the vehicle speed along the horizon.
Abstract:
In control over a vehicle, inter-vehicle communication information of a preceding vehicle that runs ahead of the vehicle is acquired, follow-up running control for causing the vehicle to follow the preceding vehicle is executed on the basis of the inter-vehicle communication information, and, during the follow-up running control, a parameter used in the follow-up running control is determined on the basis of a condition in which the inter-vehicle communication information is acquired.
Abstract:
A system for regulating the maximum speed of a vehicle (10) having wheels (11, 12) fitted with tyres and driven from an engine (13) via a driveline (14, 15, 16) with a total overall gear ratio, the system including a means such as a GPS or radar based system for determining the actual vehicle speed of the vehicle without using a calculation based on engine speed. A control unit (18) is also provided which adjusts the engine speed and/or overall driveline gear ratio so that the maximum speed which the vehicle can attain remains substantially constant at a predetermined value irrespective of the diameter of the tyres fitted to the wheels.
Abstract:
A transporter (10) for transporting a subject over a surface that may be irregular. The transporter includes a support platform (11) for supporting a load, the loaded support platform defining fore-aft and lateral planes and characterized by a load distribution. A plurality of ground contacting elements (13, 14) are coupled to the support platform such that the transporter is statically stable with respect to tipping in the fore-aft plane. At least one of the plurality of ground contacting elements is driven by a motorized drive arrangement. A sensor module (15, 16) generates a signal indicative of the load distribution. Based at least on the load distribution, a controller commands the motorized drive arrangement.
Abstract:
A system for the control of speed in a vehicle where engine braking is used. The vehicle includes an automatic engine braking facility (300) where the engine brake is applied if a predetermined threshold speed is exceeded. When used in a multi-combination vehicle where there are multiple engines (170, 182), one on the truck (168) and the other on the trailer (180), when the engine braking is applied, the braking of the trailer engine (182) is always greater than that of the truck (170), the trailer (180) acting as an anchor. Typically the engine braking on the trailer (180) is at the maximum, and only on some of the cylinders on the truck engine (170), typically 4 cylinders in a 6 cylinder engine. The operator has a manual override control wherein they can apply braking at any time, and increase the truck engine braking if need be but cannot disengage or control the automatic braking.
