摘要： A method of controlling an electric marine propulsion system to propel a marine vessel includes receiving a user-set time, determining a time remaining based on the user-set time, and identifying a battery charge level of a power storage system on the marine vessel. A required battery power is then determined based on the time remaining and the battery charge level, and then an output limit is determined based on the required battery power to enable propelling the marine vessel for the user-set time without recharging the power storage system. The propulsion system is automatically controlled so as not to exceed the output limit.

摘要： The invention relates to a method for operating a vehicle (1), wherein the vehicle (1) comprises: a driveline (2, 4) configured to provide a driving power to at least one wheel (3) of the vehicle (1) for propulsion of the vehicle (1); and a wheel brake system (5) configured to brake the vehicle (1), wherein the method comprises the steps of: receiving (S1) a control signal indicative of a request for acceleration or deceleration of the vehicle (1), wherein the acceleration or deceleration control signal is generated by an accelerator device, such as an accelerator pedal, configured to be acted upon by a driver of the vehicle (1); and controlling (S2) the driveline (2, 4) in response to the acceleration or deceleration control signal. The method comprises the steps of: providing (S3) an acceleration or deceleration threshold limit representing i) the highest vehicle acceleration that can be allowed for the received acceleration control signal in the current circumstances, or ii) the lowest vehicle deceleration that can be allowed for the received deceleration control signal in the current circumstances; determining (S4) a resulting vehicle acceleration or deceleration that is or will be the result from the step of controlling the electric driveline in response to the acceleration or deceleration control signal; comparing (S5) the resulting vehicle acceleration or deceleration with the corresponding acceleration or deceleration threshold limit and determining whether the resulting vehicle acceleration is or will be higher than the acceleration threshold limit or whether the resulting vehicle deceleration is or will be lower than the deceleration threshold limit; and when the resulting vehicle acceleration is or will be higher than the acceleration threshold limit or when the resulting vehicle deceleration is or will be lower than the deceleration threshold limit; applying (S6) the wheel brake system (5) so as to reduce an actual vehicle acceleration or increase an actual vehicle deceleration towards the corresponding acceleration or deceleration threshold limit.

摘要： Techniques are disclosed for systems and methods to provide passage planning for a mobile structure. A passage planning system includes a logic device configured to communicate with a user interface associated with the mobile structure and at least one operational state sensor mounted to or within the mobile structure. The logic device determines an operational range map based, at least in part, on an operational state of the mobile structure, potential navigational hazards, and/or environmental conditions associated with the mobile structure. Such operational range map and other control signals may be displayed to a user and/or used to generate a planned route and/or adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

摘要： A control apparatus includes: a control unit that controls torque of a rotating electric machine by performing switching control of an inverter; a temperature sensor that detects a temperature of a temperature detection target which is at least one of the machine and the inverter; and a current sensor that detects electric current flowing through the temperature detection target and has higher responsiveness than the temperature sensor. The control unit includes an overheat protection unit that limits the torque of the machine when the temperature detection target is in an overheated state. The overheat protection unit determines whether the temperature detection target is in the overheated state based on the temperature detected by the temperature sensor when an operating point of the machine is within a continuous operation region, and based on the electric current detected by the current sensor when the operating point is within a short-time operation region.
