Description

The present invention relates to a working machine with a machine control system comprising one or more control components and a working machine electrical system comprising one or more electrical and/or electronic components, wherein main control means are provided which are designed to control, supply with electrical power and/or activate at least one of the control components and/or at least one of the electrical and/or electronic components. According to the state of the art, a machine is started up by an operator pressing an ignition switch with an ignition key or a start/stop button. This activates and/or starts up all components of the machine. This means, for example, that both the machine control system and the machine's electrical system are supplied with electrical power. It is known that the machine control system comprises a master unit and/or a computing unit, and control components essential for the commissioning of the machine, such as input/output modules, a motor control unit, and others, which are connected to the master unit and/or the computing unit, for example, via a CAN bus. Steering control, e.g., an emergency steering pump control, a joystick, a keyboard, a machine display, etc., may have, or that the machine control is designed together with the working machine electrical system. In both versions, certain control components of the machine only communicate with the master unit and/or processing unit once the machine control system has granted permission for all control components essential for commissioning. This occurs after the machine control system has fully booted up, at which point the operator is authorized to commission the machine. Therefore, the operator can only start the machine after the machine control system has booted up. The machine control system takes a certain amount of time to start up. The startup time is primarily determined by the control component that requires the longest startup time. In Fig. 3 This shows a typical time sequence for starting up the machine control system. In the lower timeline, during time EZ, the operator enters the machine and activates the ignition switch or the start/stop button. This activates the machine control system and initiates the startup process, which lasts for the duration of startup time HZ, shown in the upper timeline. Fig. 3 The process is shown in the diagram. During the start-up time HZ, the operator cannot operate the machine and therefore waits for a waiting period WZ1, which is at least equal to the start-up time HZ. Only after the start-up time HZ or waiting period WZ1 has elapsed can the operator put the machine into operation. It is known from the prior art to shorten the waiting time before starting a vehicle powered by a diesel engine by bringing forward the start of the diesel engine's pre-heating process. The pre-heating process begins as soon as the driver's door is opened, for example, if the coolant temperature is below 65 °C. The vehicle's pre-heating indicator light illuminates. However, the indicator light only illuminates after the vehicle's ignition is switched on and therefore only lasts for the remaining glow time. The driver's waiting time after taking their seat and turning on the ignition until the glow plug indicator goes out is thus reduced by the time it takes them from opening the driver's door to taking their seat. However, the current state of the art has several disadvantages, including the fact that the process described above cannot be modified and only the glow plug cycle runs parallel to the start-up process. Applied to a machine, the startup of the control components would still require a waiting period, as explained above. Against this background, the present invention aims to improve the above-mentioned working machine, particularly with regard to reducing the commissioning time of the working machine. This problem is solved by the subject matter with the features of independent claim 1. Advantageous embodiments of the invention are the subject of the dependent claims. According to the invention, activation means are provided which are designed to be able to activate at least one of the control components. Preferably, it is provided that at least the control components of the machine control system essential for commissioning the machine, or the entire machine control system, can be activated and/or started up by the activation means. The control components essential for commissioning the machine are preferably one or more of the following: master unit; peripheral control; input/output module; joystick; keyboard; motor control; display; in particular, a machine display; steering control. The time required to start up the control components of the machine control system, i.e., the time needed until the machine control system releases the machine for operation, can represent at least a portion of the operator's waiting time. Preferably, the aim is to shorten this waiting time for th
